A few questions...

SOme questions:
1. is @Bopp: Do you hate me? (sorry)
2. Magnus vs Alchemer is FSC: Which is better, and does the Magnus stop zombie's attacks?
3. Cutter vs Flourish: Uhhhhh, I think they are equal:
Cutter pros/cons:
Pros:
10 cut combo
Can poison (at 4* vile striker)
INSANE DAMAGE
Cons: Shadow slice (or bite) does less damage than original slice
Has a VERY dangerous charge attack
Flourish pros:
Very fast ASI
Good damage per slice
Snarble Barb line has shotgun charge attack thats OP against trojians
Cons:
Flourish line has a not-so-good charge attack
Lunges you forward (can be good thing to)
4. Cutter vs Brandish: Which is better? (already have a combuster but not a cutter, wondering if I sould get one.
5. Final Flourish vs Barbarous Thorn Blade: Which is bettter?
-Nert
P.S. I'm truly sorry, Bopp

I don't have alt knights. I only have one. :)
Aren't alchemers better in FSC because of the devastating charge?
Oooohhhhh... how does DVS attack faster than WHB? (my brother has WHB and after I showed him the data, he's now gonna get DVS xD)
I think BTB is better because of the charge... or is it?
Flourishes attack the fastest per normal slice for swords in the whole game.
Isn't it as good as a brandish? Cause the cutter does more damage overall. Or if thats not true...
NEW QUESTION... TO ASK...: Is Cold Iron Vanquisher worth it?
-Nert

Cutters most certainly do not do as much damage as a Brandish or a Flourish. Cutters are rather meh overall.
The real problem is that Cutters just push everything around. It's really hard to get all the ghost strikes to hit the target. Brandishes on the other hand can reliably hit their target multiple times, and has a good AOE clearing charge that is very safe to use. Flourishes also have their great first swing to quickly hit multiple enemies in one swing.

Aren't alchemers better in FSC because of the devastating charge?
Alchemers do have devastating charge attacks. But so do magnuses. And so do autoguns.
how does DVS attack faster than WHB? (my brother has WHB and after I showed him the data, he's now gonna get DVS
DVS attacks faster than WHB because the designers tuned it that way. Also WHB interrupts more than DVS. There are subtle asymmetries in the game, that make things more interesting. I do not recommend getting both swords.
I think BTB is better because of the charge... or is it?
This is covered in my sword guide. Search the wiki for "Bopp's Sword Guide" if you don't remember where it is.
Flourishes attack the fastest per normal slice for swords in the whole game. Isn't it as good as a brandish?
They're both great. Before the flourish range was nerfed (in 2012?) I'd say that they were equal. Now I'd say that brandishes are slightly better. But really you use them on different enemies, so it's not a valid comparison.
Cause the cutter does more damage overall.
More damage than what? Against which enemies? I have better swords to use against any enemy than my DVS and WHB.
Is Cold Iron Vanquisher worth it?
No. CIV is one of the worst swords in the game. As my sword guide explains, it's worse than Leviathan Blade. And you shouldn't get Leviathan Blade either, because you should just use Fang of Vog if you want that charge attack.

Fang of Vog is soo hard to get :( which is why I'm probably gonna get CIV. And also, its charge attack has abit lesss knockback making it hit twice against normal lightweight enemies, which is always better
More damage than Flourish against neutral enemies
-Nert
P.S. Is there any other way to get FoV other than the Almirian Seals? (or someone that sells it for not-so-expensive)

While cutter is less compared to other weapons, it still maintains a good dps for a single target, you do need a good flow though, know when to stop / shield (may want to corner the monster into wall first due to accidental shield bump). It's like a last showdown between you and *insert one here* (Battlepod/Royal Jelly/Vanaduke/Giant Lichen Colony), then you unsheath your cutter and slash the heck outta that boss until last pieces shredded out of their body.
The cheapest way to get FoV is by getting enough tokens to trade it, other ways are more expensive.
And FoV from tokens is far cheaper than making CIV from scratch. That is, when you get accustomed with FSC.

Just to unbind the Fang of Vog is 4000 energy, which is over 300,000 crowns.
If you want an item to help you deal with Firestorm Citadel, there are so many weapons that would work leagues better than a Cold Iron Vanquisher. Off the top of my head...
- Combuster / Glacius / Voltedge
- Divine Avenger
- Warmaster Rocket Hammer
- Blitz Needle
- Nova Driver / Storm Driver / Hail Driver / Magma Driver

Fang of Vog is soo hard to get :( which is why I'm probably gonna get CIV.
In your other threads, you keep mentioning how you are unable to accumulate money, which makes it hard to get new 5-star items. And now you have chosen to obtain one of the worst 5-star items, for no particular reason. Giving advice to you is very difficult.

First and foremost- don't vendor any of your stuff to get either of these weapons. They're good but not earth shatteringly so.
Cutters are incredible when pulled off correctly, but there is no place for them to be incredible and they're relatively lackluster when it comes to the typical meta of damage types. Dread venom striker has better DPS than brandishes vs effective targets if you give it enough damage boost, but giving it enough damage boost is often impossible and never matters. It's better to have a little bit less DPS in the extreme condition require and an area charge + superior 3 hit combo. If cutters get buffed they'll become worth it for sure.
Flourishes are very mobile and have a very quick first strike. You don't use them for their DPS because there are better items for that, but rather for their speed and attack pattern. This makes them a good early-game counter for devilites and a good late-game utility sword for fighting things like grievers.
For actually getting better at the game, you should pick up a flourish of some sort at some point. Most people like final flourish because that has better damage and doesn't mess around. They're not wrong and they're especially right for earlier levels where they'll be relying on their flourish. I like rigadoon because the enemies I use it on are typically weak to stun, and being able to get off a stun can give you enough time to charge a handgun for the kill or focus on a different enemy and come back. The stun is rather underwhelming if you aren't planning around it or don't need it.

@Bopp first of all, forget the unable to earn money thing. I can earn. OK? Second, I'm keeping it at 4* heat lvl10. Which is NOT hard AT ALL (Tier3 runs rules)
Nowww....
I agree with Poopsie, but... its not as bad as Fehzor said, is it? And what do you mean "Giving it enough damage boost"? (I have max damage bonnus for swords) Cutter is a good weapon for FSC isn't it? And now that I've got enough convintion from this thread (even the cons) I'm gonna vendor my cobalt stuff (lol havn't sold them yet) and get DVS (or, should I say to you Bopp, Vile Striker). I have a Flourish (Furious Flamberge, and yes Bopp, it is 5*) but it does crap damage. And Traevelliath, I have alll of at least one type of all the weps u listed.
And can someone delve deeeper into the Magnus question?

As in max damage for swords + maskeraith's deadly shadow cloak + an attack boosting orb. It has to go through a ton of resistance to deal damage, since it deals 2 hits of normal damage and hits faster than that to boot. As you increase damage, resistances start to look smaller and smaller.
Basically-
(damage prior to resistance/buffs) * (damage boost) - (resistances that don't change) = damage done
As the damage boost goes higher and higher towards infinity, the non-changing resistances start to become more and more negligible. Eventually, what things are weak to doesn't matter at all and the damage prior to resistance/buffs starts to become much more meaningful. Dread venom striker has a lot of that damage prior to resistance/buffs, but even more resistances that don't change. Hypothetically, dread venom striker does its job when buffed to the extremes better than the brandishes do its job but in practice this is never actually useful. So don't bother with it until after you've bothered with other gear and are established.
At some point we'll probably end up with an area that really benefits from having dread venom striker. This would likely require a huge variety of monster types, respawning gremlin menders, many shielded enemies (trojans/deadnauts but we'd need more than just those) from different families that somehow have a ton of health, and some large reason not to just use blitz needle + grim repeater; i.e. the area would have to REALLY encourage the use of other kinds of damage rather than just damage types. I would not however, worry about such an area in the meantime.

Erm... What's the point of asking questions if you're going to ignore the answers we give? Bopp, Fehzor, and myself have stated that the Cutters do rather meh damage. So why are you still asking us for our opinions on Cutters?
"And Traevelliath, I have alll of at least one type of all the weps u listed."
I think you missed the point of my post. If you have any of those weapons, then you don't need another weapon for the sake of FSC. All those weapons will out-do Cutters and/or the CIV in FSC.
The only times I use my Dread Venom Striker in FSC is either for the style points, or on Vanaduke's Mask phase. Because of it's insanely fast charge time, you can quickly douse the mask in water, and then poison it with a charge combo while others fire away with Blitzes. Even then, a Plague Needle would probably do the job just as well except with more damage. DVS just does it with a dramatic flair.

Didn't I hear that the Acheron does more damage to undead than the CIV? Makes the uselessness of the CIV show even more...

Halandin, Acheron does not do more damage to undead than CIV does. See the link in post #1 above.
About DVS: Fehzor's theory about how damage boosts is correct. Extra damage from type (e.g. elemental against undead) is constant, whereas damage bonus (e.g. Undead: Medium) is proportional. In theory, damage bonus could overwhelm extra damage from type, with sufficiently hard-hitting weapons or sufficiently massive damage bonus. In practice this does not happen, except perhaps in extremely special scenarios with sprite skills. To see a more typical scenario, you just have to read the link in post #1 above. DVS does much less damage per second than brandishes.
Nertgvv: I'm sorry that you got Furious Flamberge. It is nowhere near as good as Final Flourish/Barbarous Thorn Blade, as my sword guide explains.

Oh yes, I should have mentioned the Furious Flamberge. That's a trap weapon-- there aren't any enemies that are weak to both fire and piercing, and the bulk of enemies that are even effected by piercing resist it as well. Zombies are the exception, but they don't benefit from the fire so much due to their high health and the presence of ash of agni, combuster and even fang of vog.
Flamberge is only worth crafting for the sake of collecting weapons or future proofing yourself; if it gets changed in some way (my suggestions have been to make the charge switch it over to being elemental for a while, or just make it shadow damage to begin with) then it could become much more worthwhile. The other out for it would be a new set of common piercing + fire weak monsters, which is also a stretch.
But don't vendor your flamberge. Just because it's bad now doesn't mean that it'll be bad tomorrow, and it still works for the bulk of levels, just worse than it could be working. Instead, craft something else that is new- then you'll have a flourish that functions and a new weapon that functions.

Now THAT is how you guys just helped me a ton.
@Fehzor FF is good against players, they are weak to piercing and fire xD. Should I get a Final Flourish/BTB? (for lockdown/vana)(prob not vana xD) And I don't think flamberge is EVER going to get buffed.... its a wast weapon now, and I'm wondering why I'm still using it for lockdown, even Grand Flourish/Dark Thorn Blade is better.
@Bopp DVS only does 10 less damage against neutral Combuster. Not much, is it? Also, how does Faust do so less DPS? And it seems that DVS still does OK DPS. Why are you all saying that its not good? (I didn't get it yet xD)
@Bopp and Fehzor Also, if damage bonus CAN overwhelm special damage, can't you just stock a Combuster and get damage bonus vs undead/construcs max and then its OP?
@Haladin uhhh that is not really possible, as the Acheron is shadow.
-Nert
EDIT: Woops that was wierd wording for the Bopp and Fehzor part. If you didn't get it: It means that can't you just stock UV's on a Combuster and get damage bonus vs undead and construcs MAX and its OP?
P.S. I suck at spelling

It's true that DVS does almost as much DPS as Combuster against neutral targets, depending on the depth and damage bonus. But Combuster also has vulnerable targets, where it does much more DPS. But doesn't Combuster also have resistant targets, where it does less DPS? Not really, because you use your other weapon on those targets. And Combuster has an insanely powerful charge attack, whereas DVS' charge is nearly useless.
It's true that DVS does about the same or more DPS than Gran Faust, even against vulnerable targets. But Gran Faust has a much better chance of hitting multiple targets, which dramatically increases its damage output. Also, Gran Faust can knock those targets away from you, keeping you safe. It's best in those situations --- not situations where you're trying to kill one monster quickly.
These are all important considerations in planning a sword loadout. That's why they're all covered in my sword guide.
So is DVS' damage output okay? Certainly. Is it "INSANE", as you claimed in the original post? Certainly not.
I'm not sure what you're saying about a UVed Combuster. You mean getting damage+6 and the damage type bonus? Yes, I do that every day. Do you want to know the DPS produced by such a setup? Then look at the last table in the wiki article that I linked in post #1.

The damage bonuses you get from using say, black kat set, unique variants, armor.. those all max out at 1.24 which is not nearly enough damage to overcome monster resistances and negate them like I said. The attack orbs, drakon, maskeraith.. those stack with that 1.24 bonus and can bump you high enough to the point where you start to see it happening. At that point though, you're probably going to kill whatever is in front of you regardless of whether you're using a brandish or dread venom striker... and the requisite boosts tend to be quite fleeting, so you only get about 2 combos worth of absurdly high damage and then you're done.
It's also worth noting that per combo, dread venom striker has A LOT more resistance going against it than does combuster.
DVS: 10 hits * normal resistance
Combuster: 6 hits; 3 * normal + 3 * specialized resistances
So even if you DID stack the damage onto combuster and it somehow went WAY over the measly 1.24 bonus from damage: max, stacking that damage onto dread venom striker would be more lucrative in terms of reaching the highest possible sword DPS.

Than why does Bopp say its so bad when you say its lucrative? Doesn't that mean the damage Max! on the DVS is ALOT better than it on the Combuster? Or is it?
And Bopp, I use a gun and a sword, which is the reason why I am considering the DVS.
EDIT: Should I get a BTB/Final Flourish or should I get DVS/WHB?

Fehzor: "Oh yes, I should have mentioned the Furious Flamberge. That's a trap weapon-- there aren't any enemies that are weak to both fire and piercing, and the bulk of enemies that are even effected by piercing resist it as well. Zombies are the exception, but they don't benefit from the fire so much due to their high health and the presence of ash of agni, combuster and even fang of vog. "
Waitwaitwaitwaitwait, did you just say that the whole beast family and the whole fiend family is resisting fire much better than other monsters do or did I missunderstand something?
I once wanted to craft that fiery flourish once, but I stopped at 3 stars that time because I didn't like the forward-thrust with a too small hitbox (a fact that made me use a Leviathan Blade vs fiends more effectively (exsp. vs Greavers) and more fitting better to my my playstyle. Btw: I also disagree the statement to get FoV over Leviathan, since FoV burns yourselfe and Leviathan can be spammed and either keep monsters at bay or hit a nice damage that kills too carefree Greavers).
Though I still am interested in weapons that can deal fire and would craft the higher versions of that fiery flourish sooner or later - but.... if it is "a trap" as you said, then I should leave this aside.
Also, I need to confess that I didn't look close to monster's resistance in stati yet. I also was wondered when i recently did set fire monsters on fire and froze frost monster's feet - things I didn't thought it would be possible.
Could you give a useful link for this as backup for monster's resistances?
Side note: I got a BTB, heat level 1 right now, it it does matter at any point in your answer.

http://wiki.spiralknights.com/Damage/Monster_resistances
Thats for what monsters resist what.
And don't get the Furious Flamberge, it does 100 less damage than the BTB/ Final Flourish, its soo bad, you won't believe it.

You missunderstood my question.
The damage type resistance is a thing I am completely aware of.
By how I understood Fehzor's post, I guess that wolvers, beasts, devilities, trojans, gorgous, greavers and healing butterflies are more resistant to fire than zombies and other groups of monsters (not fire-enemies).
My question does completely refer to the status, *not* to to the four damage kinds (Normal, pierce, elemental, shadow).

Than why does Bopp say its so bad when you say its lucrative?
He's saying that in some theoretical situations DVS will outdamage Combuster. These theoretical situations go way beyond damage+6. He's talking about damage+6 and having multiple sprite skills giving you boosts at the same time. (Those boosts let you go over +6.) So it can probably happen, but it's hard to arrange, you can't sustain it, and you certainly shouldn't be planning your loadout around it happening consistently.
Doesn't that mean the damage Max! on the DVS is ALOT better than it on the Combuster? Or is it?
No. This has already been answered for you repeatedly. Just go to the link I gave in post #1 above. Scroll down to the bottom. Look at the table, which is damage+6 at depth 24. The numbers for Combuster are bigger than the numbers for DVS.

Here is the most detailed study of status resistance in monsters that I know of. The Google spreadsheet linked in the original post lays out three or four levels of fire resistance in monsters. It does not go by family.

DAWG-
Combuster/acheron will do better than DVS at what DVS is doing almost all of the time, and has a significantly better charge to boot.
There is ONE SCENARIO where this isn't the case, and it's the one I and now Bopp told you about regarding attack orbs and sprite skills that is never applicable unless you're derping around in the end game experimenting with normal damage loadouts. That's why I told you not to immediately go for it or anything.. the only reason I brought it up is because it's basically DVS's big claim to fame.
---------
@Jenovasforumchar
Yes. The monsters in question (except for the wolvers, which aren't weak or resistant) are all resistant to fire, and with the exception of devilites and trojans weak to stun.
https://docs.google.com/spreadsheets/d/1FGf7OsZNetwQIe2MDkc947EWRPEzqBhd...

So basicallly DVS sucks and I shouldn't get it. And its claim to fame is a thing thats not possible. Whooye. But Bopp said to try it. Should I?
Um, Also, should I get a grand flourish? Or should I keep using my Flamberge?
-Nert
P.S. In chawkthree's demo video (or someones or the wiki or something) they said that getting damage bonus on a striker is beastly. From what you guys just said, its not true. Am I correct?

So basicallly DVS sucks and I shouldn't get it.
No, DVS does not suck. It's *okay* for damage, and *poor* for tactics (e.g. attacking one monster while avoiding another monster).
And its claim to fame is a thing thats not possible.
It's possible, but not very likely or common.
But Bopp said to try it. Should I?
Other posters should give you their answers, but let me just clarify mine: Much of the fun of Spiral Knights is trying different weapon styles. Therefore you should try *every* weapon style, including catalyzers, blast bombs, troikas, and cutters. Therefore you should try cutters.
In chawkthree's demo video (or someones or the wiki or something) they said that getting damage bonus on a striker is beastly.
It's not clear what "beastly" means, but I've given you actual damage numbers, which (almost) objectively show that DVS with big damage bonuses doesn't inflict remarkable damage.

Don't sigh at me. I just have dumb questions.
Anyways... beastly means insane, basically. And.... yeah, I guess it doesn't do much damage. But.... for now, I think I'm gonna get one, though right at this moment, my brother is screaming at me saying "YOU CAN"T USE CUTTER, ITS TACTICS ARE TOO HARD AND YOU'LL DIE TOO MUCH, YOU *******" sooo.... yeah, can you prove him wrong?
And can you please awnser my "hould I get a grand flourish? Or should I keep using my Flamberge?" question?
-Nert
P.S. My brother is an a**h***

And can you please awnser my "hould I get a grand flourish? Or should I keep using my Flamberge?" question?
Probably you should not get another piercing sword for a while. Probably you should try some other weapon styles. I keep saying "probably" because I don't really know which weapon styles you've tried.
Once you've tried all of the weapon styles, and if you've decided that piercing swords are useful, then you should get a better piercing sword.

Iiiimmmm just gonna get the DVS. Also gonna wait for Fehzors respons too
One last thing: Is Fang of Vog good or is Combsuter better?

One last thing: Is Fang of Vog good or is Combsuter better?
Like most of your other questions, this is handled in my sword guide. See the section on elemental swords.

FOV eats immobile/large enemies with the charge and gets fire chance on every hit making it a good hit and run weapon and a priority enemy elimination weapon. The charge can light you on fire so a bad choice unless you use fire resistant armor.
Combuster has a much safer to use charge and promotes spamming that charge. It's safe, powerful, simple, and rewards the least intuitive and least risky strategy.

Have another question I though of.
Is the Rigadoon worth getting? Not much enemies (quicksilver, etc) are resistant to stun. And the resistant ones are strong to piercing. So is it good?

Quoting Fehzor from this very thread:
"I like rigadoon because the enemies I use it on are typically weak to stun, and being able to get off a stun can give you enough time to charge a handgun for the kill or focus on a different enemy and come back. The stun is rather underwhelming if you aren't planning around it or don't need it."
Quoting Bopp's Sword Guide:
"These swords [Flourishes and Snarble Barb] kill piercing-vulnerable monsters so quickly that there is usually not much point in also inducing a status; you would rather just have as much damage as possible."
As for my own opinion:
No. Just kill them with the sharper stick. No need to add anything fancy.
No. Rigadoon does a lot less damage, and has such a low chance of stun that the loss in damage simply doesn't make up for it.
Sources:
http://wiki.spiralknights.com/User:Jdavis/Swords
http://wiki.spiralknights.com/Fearless_Rigadoon
Ingame guild discussion from last year about the Flourish line, and how utterly useless the fire/stun variants line are

The rigadoon has a much higher chance of improved stun when used against targets that are weak to its stun.
See: http://forums.spiralknights.com/en/node/93505
My argument is that I don't bring flourishes for damage, but for the utility of having a wide arcing swing and jabbing motion. I can either have a better version of that, or I can have stun. If I plan to use my sword against those enemies that are weak to it, then I'd often much rather have the added stun utility than the extra damage. When I go to smack a griever, it doesn't matter how much damage I'm about to pull off, just that I hit.. but if I can get off the stun, then I've REALLY messed up that griever, not just canceled one of its attacks.
I think it's worth getting eventually, but only when you know exactly how it operates and are building higher level loadouts that could make use of it.

Does the rigadoon have a much higher stun chance on the charge?
If it does I could see it being a charge oriented flourish weapon, if not you'd be better sticking with the regular or snarble version.

@Holy-Nightmare
Even if it did, a Final Flourish charge kills most pierce-weak enemies outright (except maybe Trojans who are resistant to stun to begin with). If you're looking for a weapon to cause an AOE stun on neutral targets, then I'd point you to the Sudaruska.

Right
Forgot about da ol'Sud
Though its attack speed is VERY bad. (Slower than sealed sword lines) Is there any use of the normal attacks?
EDIT: In that thread that Fehzor showed me, it seems that the Rigadoon's stun chance isn't that bad. Can someone confirm?

Suda is a bad weapon but a great utility.
You can pair it with other weapons or players that rely on enemies being in a certain place to deal more damage.
It works with Tortofists since it can position the enemies under the incoming spikes of the charge.
It can help Vortex Bombs by either helping them collect more enemies or by throwing in a charge attack.
Leviathan and FOV users can get more hits on their charge against enemies stuck in a corner.

Ahh. Ok.
Than is Triglav more utility or is Sud more utility? Cause JDavis voted Sud.

Suda doesn't get status on its regular combo this means you have more control over enemies movement from any angle.
Trig gives status on charge (like suda) and the combo end (unlike Suda). This can be a problem since enemies get harder to flinch at deeper depths, you could end up with an attacking enemy frozen dangerously close to you. To counter this use Trig combos from behind so that if you do freeze them they can't hit you. If you freeze them you can get a free charge attack on them (or someone else can).

Than will you recomend Triglav or Sudaruska?
I think triglav is better...

That depends on how you intend to use the weapon lol. If you're just pushing and doing damage like you usually are, sudaruska is better. If you're spamming charges in a party that's set up to cope with ice, then triglav is going to be better.
Basically-
Sudaruska = Normal hits are nicer in general
Triglav = Charge hits are nicer in general
Though that isn't to say that Triglav's normal hits are bad or that sudaruska's charge is way worse. They're still very similar weapons most of the time. So either get whichever one you think is more awesome, or whichever one fits the normal/charge difference above. If you are getting it, that is.

Triglav is in my opinion worse. Freeze is cool and all but a major reason you'll want to use a Troika is for the knockback. Stun is all helpful, but with random freezes, it gets really unpredictable. Often, you'll freeze an enemy right up in your face and they can attack you before you even recover after the combo animation. You can play with this in mind, but if you do you will often be relying on dodging your enemies instead of using your knockback to manage them, which isn't exactly the idea behind a sword with immense knockback.

Well, I'm going to be using the charge more... so Triglav I come!
Thats really all dem question I have for you guys!
Thanks for everything,
Nert
1. Not as far as I know. :) It's possible that you have alternate knights that I dislike, though.
2. Magnuses and alchemers are both great in FSC. Probably magnuses are better at tearing through crowds. I would have to run tests to form a stronger opinion.
3. I don't agree with a lot of these points about swords. You might want to look at data sets such as this one.
Cutters don't do "insane damage". They do so-so damage. And to "cons" I would add that you have to get right up in the monster's face. That's bad because meanwhile other monsters may munch you.
Flourishes don't have "very fast ASI". They do more combos per minute, but fewer strokes per minute, than cutters. Flourish charges are also very effective against trojans; it's the smaller enemies that you have to worry about with those charges. And I would add a big "pro": The first stroke of the flourish combo is wide, so that you can hit and interrupt many monsters at once. This is great when fighting 6 wolvers or 8 greavers or 3 devilites at once. By the way, all of this is in my detailed sword guide. Also I would add a "pro" for non-normal damage, especially against the nastiest monster family in the game (fiends).
4. You should get a cutter because trying different weapon styles is fun. But no, it is nowhere near as good as a brandish (even ignoring the difference in damage type).
5. FF vs. BTB is covered in my sword guide. But of course other players may have other opinions.
