Golden Sun gate is your golden opportunity

...to finally stop whining about how hard devilites are and just learn how to fight them. You get a fiend-themed stratum in every tier, so they'll scale to whatever difficulty you want. Except, you know, for actually being very hard, which they don't reach even in tier 3.
Also, the loot is great. From one run, I got:
1 dragon scale
1 chroma tear
1 meteor mote
1 miracloth
2 mugs of misery
1 silver coil
1 warp dust
6 bushy tails
2 drake scales
3 fine fabric
1 unstable core
5 monster bones
7 green shards
1 primal spark
2 grim sparks
1 forge spark
There were a lot of other things that I'm not listing, because they were less valuable. That's well over 20k in materials from a single run--not counting the crowns. The key is that, even though there is only one five star material there, there are two and three and four star materials that are valuable and drop in abundance.
Oh, and did I mention that I only did six levels that run? It's not like I cleared the whole gate. I started at Emberlight, did six levels (not counting Basil or Emberlight itself), and decided that my thumb was sore so I'd stop. If that sort of loot isn't enough to motivate you to learn to fight devilites, then I don't know what will be.
That's not what the whole group got, either. That's just what I got, personally. I was solo for three of the levels and part of a fourth, however.
Okay, so I did do three danger rooms solo. But still.

I was just grouped with someone in the Golden Sun gate who got a shadow steel, two ghost bells, and two mugs of misery. That's over 10k worth of materials right there.
Oh, and that was all in one level. In the rest of the run, he got a lot of other loot, too. And he wasn't solo, as I was in the group as well, and also got decent loot for the level.
Devilites are fine. Learn to fight them. :)
Thanks to my new mega magnus, those fiends aren't a problem no more. Thou I still missing shadow defense gears :x a divine veil can only protect so much.
ps. bigfoot, i'm still waiting for your guild invitation :V
The only hard part about fiends is when they sync up their projectiles.
It's like this:
Spiral Knight steps on Party Button.
6 Devilites spawn.
6 Devilites start their projectile attack.
Because the Spiral Knight only has a Barbarous Thorn Shield or a Wise Owlite Shield, the six projectiles easily break the poor knight's shield.

Complain about Fiends.
End.
not with a 400 ping, the throw animation is shorter then 500ms so there is no time to dodge, most other attacks are 1 second so you can still dodge and shield. While a low ping player has 1 sec to react we high ping players have just .6 to react the game is much harder for us, but devilite are impossible to react too with a high ping.
Uhm...why do people keep telling other people water is wet?
and in this case they try to convince them it's even wetter when THEY touch it.
you must be a magician! :O
Oh then if they are supposedly so easy to beat, how do you do it? Share your secrets with us, master.
I got 10k crowns in a single Golden Sun gate run...that's all,NOT including the materials
Get piercing weapon
have some type of ias bonus helps
have decent shield, shadow helps a lot
attack right after they throw their chairs and stuff XD
go for the mad ones first , usually brighter in color and throw pitchforks
then go for the ones that dont attack you (boss or ones following the boss)
if you kill the lower rank ones first then the bosses turn to lower rank ones = more furniture to dodge
go in that order and it simplifies it a little bit :D
@Rigwald that's why you don't complain when a bomber joins your group. Goes like this:
-Plant bomb.
-Knights step on Party Button.
-6 Devilites spawn.
-6 Devilites start their projectile attack.
-6 Devilites go flying off in a massive explosion.
-Laugh maniacally :D
If six devilites spawn and throw something simultaneously, you can get half of those to miss even while shield crawling (assuming they aren't right next to you). And then after they've thrown, they're ALL vulnerable. I don't think you've played many fiend strats.
No, what makes devilites terrible is the chance of nonstop, unrelenting, unending attacks from over a dozen enemies, a situation which occurs commonly in fiend strata. When their attacks are NOT synchronized is when it's impossibly deadly. One or two throw at once, and if you try to strike them right after they've thrown, you get hit by projectiles from one or two of them somewhere else. It's just an unending rain of super fast projectiles that travel across the screen that makes them the most hated enemy in the game because, if you're solo especially, there is little to nothing you can do to avoid being hit at least a few times.
I WISH they all attacked at once. That would make things a whole lot easier for me. I have all skelly gear, dread skelly shield, and a flourish. And S6 fiend levels STILL give me trouble. I'm a pretty good player, as well. The best you can do is strike once, shield, repeat until dead. Hugging the edges of the field sometimes helps, as far away devilites in the opposite corner sometimes won't attack. Fiends in tiers 1 and 2 are nothing to worry about. In S5 they're dangerous, and in S6 they can get downright ridiculous.
I got a Snarble Barb just because of Devilites. Then I started using my Angelic Mail and an Angelic Helm, which I'd originally got strictly for costume purposes. The combination of Piercing damage, a Medium damage bonus to fiends, and Shadow defense have helped quite considerably. Even with 2 or 3 in a group, regular Devilites go down in two hits now. As an added bonus, the same gear also makes Greavers fairly trivial. (Although there is a downside. I get set on fire rather easily, and if I don't have remedy capsules on hand it really, really, really hurts.)
I still find myself shield cancelling the first attack of the Barb though. It's quick, hits a fairly wide arc, and its just safer that way.
Tips:
Always kill the Overtimers first. They are usually pinkish, they glow, and the have a pitchfork.
Try not to kill the Pit Bosses if there are any of the little green Yes-men around. If you do, then the Yes-men will become Overtimers.
Do kill a Pit Boss if he's turning Devilites into Overtimers. When the Pit Boss dies, one of the other regular Devilites will be promoted to a Pit Boss. Hopefully that Pit Boss will make Yes-Men instead. If a Pit Boss is making Yes-men, you can afford to leave him alone. Neither of those types actually attack you, so you can concentrate on killing the other guys. On the other hand, if you have the right weapons on hand and can kill them quickly, forcing a chain of Pit Boss promotions can simplify a fight drastically. Just bear in mind that they have considerably more health than the other Devilites, so groups will need to focus them down. (I actually use this approach when I'm solo, and I can just about do it in groups of 2 by myself. In groups of 3 or 4 though, I need help for this to work.)
Bear in mind that if there are only Pit Bosses remaining, they will all revert to being regular Devilites.
Devilite projectiles are pretty fast, but they don't auto-correct their aim very well. I've found that it helps to keep your distance initially, and move mostly perpendicular to their lines of attack. Charge straight in after they've thrown their projectiles. It can also help to use guns to herd them into the same general area, so they aren't attacking from too many angles.
Honestly though, perhaps the best thing you can use on Devlites is the Spine Cone series of bombs. It deals piercing damage, it knocks down and interrupts anything they thought they were doing, and if they survive the explosion it doesn't knock them half-way to Dubai, so your party members can easily finish them off.

Third post of the thread.
"No, what makes devilites terrible is the chance of nonstop, unrelenting, unending attacks from over a dozen enemies, a situation which occurs commonly in fiend strata."
Not from a dozen fiends, though. I guess you could cram a dozen enemies into a third arena, but those are mostly mecha knights or gremlin demos or something. Maybe you could get a dozen at once in a Sinful Steps level if you pull it wrong.
It's not that devilites are easy. But they're certainly manageable. Greavers, on the other hand, are just plain nasty if you get too many of them at once.
I just did the sixth stratum of Golden Sun gate in a group that was three at the start of the stratum and four by the end. We had a total of three deaths for the whole group in the stratum, and a bunch of health capsules left over at the end. I've done a fiend-themed sixth stratum solo without dying before, too. Yes, it is relatively hard as strata go. But it's doable.

See this is why you can't just say something's "easy" like it should be universal.
I can handle devilites fine, and I think (unlike many others) that Greavers are a cakewalk even when you have several on you, but it's Retrodes (who I see people not complain often enough about) in Tier 3 that don't get knocked down or stunned enough, and can pull out-of-screen laser to do serious damage and status inflictions.
I'm not saying it's totally impossible. But it's far more difficult than it should be, and it's a fake kind of difficulty. It's not a difficulty that, with sufficient skill, you can get by without a scratch (hypothetically it's possible with the right levels). If there exists a level where it is virtually impossible to go without taking a single hit regardless of skill, then it's fake difficulty. You mentioned greavers: their ability to inflict status effects through a shield is also fake difficulty, because no amount of skill on your part can stop that effect from occuring (short of running away at the risk of being hit or luckily having the right resists). Shock especially, but that's a whole different topic.
Also, yes, definitely around a dozen fiends at once can be found in standard levels. I don't know the level names offhand, but the ones where you need to walk around in a spiral of spike traps and unbreakable walls to hit a ghost block are the ones I mean. Once you release the walls, you now must fight probably a good 12-18 devilites (The range is there because of the "boss" fiends that don't attack, but may become fighters later; also those numbers are offhand, not exact). As I said before though, if you're by yourself, keeping to the edges after smacking the block usually helps a lot.
And don't forget the combos. It's not just about fighting only fiends. You throw those bad boys in with Kats and Greavers and lordy lordy, it's going to be a sucky day. Nothing is "impossible" and really, no one ever claimed fighting fiends was; but it's harder than it should be compared to other strata, especially considering the relatively low payout and heat you get from them (devilite levels pay poorly; not including materials here).
At the end of the day, though, everyone agrees: they're not easy. Devilites suck. And you can go and chastise people who may have died a couple times on those levels by themselves and just QQed about it and never went back; that's fine. But the tone of your post to me was "if you guys hate devilites you all suck and need to l2play," essentially. I know you likely didn't intend it that way, but that's how it sounded to me.
So what you're saying is the price of all those mats are going to fall like a rock?

"You mentioned greavers: their ability to inflict status effects through a shield is also fake difficulty, because no amount of skill on your part can stop that effect from occuring"
The first hit is about your skill. The problem is that once they get that first hit off, there often isn't much you can do to avoid taking several more hits. No other mobs in the game are like that. Even among other mobs that apply conditions, that can be countered with a remedy capsule, but that doesn't work against greavers, as it will immediately be reapplied.
"Also, yes, definitely around a dozen fiends at once can be found in standard levels. I don't know the level names offhand, but the ones where you need to walk around in a spiral of spike traps and unbreakable walls to hit a ghost block are the ones I mean."
You're probably talking about devilish drudgery levels. If you're an idiot about pulling, then yes, you could have to fight 12 of them at a time. But they can nearly always be pulled apart so that you only have to fight two or three at a time that actually attack you. That's a lot more doable.
"And don't forget the combos. It's not just about fighting only fiends. You throw those bad boys in with Kats and Greavers and lordy lordy, it's going to be a sucky day."
Some of the dark city levels, notably sinful steps and ritual road maps, are pretty hard. But that's a manageable sort of hard, whether solo or grouped. A group composed entirely of very good players, regardless of the group size, will get hit now and then on those maps, but rarely have anyone die.
It's an entirely different sort of hard from having two rocket puppies and four greavers pop up at the same time in an arena that you're trying to solo. If it's sixth stratum and they all see you immediately and you don't have anything pre-charged, you're probably dead, no matter what you do and no matter how good you are.
If you're a bomber (or at least a bomber with a gun) a vortex bomb does wonders against grievers and devilites alike, especially with the Polaris, making devilte dodges basically impossible within the suction. My brother even commented how it seemed like i was just steamrolling them despite the fact that i had no sword at all :P
Fiends fall just as easily as most monsters. Then again, I adopted the snarble barb fairly early on.
What's nuts is those lumbers that stun you AND shock you.
I think the only monsters I struggle with are those tin-can-head constructs. I just can't get my timing right. Do they sometimes just have an extra swing in their combos? I always drop my shield too soon.

Fiends attacks randomly.their attacks are not timed.it's actully not recommended to use a snarble barb because of it's lunge.once you lunge, a fiend can hit you with a chair and take out three hearts.I used my barb only once to test it out.I am better with three swing swords like caliburs.I usually charge up my we peon and release it on the fiend.

It's not that golden sun is great because the monsters there drop rare loot. It's that the loot is rare because people don't like facing those monsters.
I clicked on the topic thinking the thread was about how Golden Sun tier 2 has the potential for 3 arenas plus the Jelly Palace. $$$
But on topic, I hate Greavers, but I'm getting better at Devilites. I generally try to do a fiend stratum every couple of days for practice. It's helpful when it comes along with my JK runs. I do need more shadow defense armor/shield.
What really irks me is when the fiends sneak into my undead levels.

"It's not that golden sun is great because the monsters there drop rare loot. It's that the loot is rare because people don't like facing those monsters."
There is quite a bit of truth to that. That's why I'm considering that next time someone whines that devilites need to be nerfed, I may offer to sell him some mugs of misery or shadow steel, since he can't get his own.
ill take fighting retrodes over devilites in a roomful of spikes any day
I got a full Dread Skelly Set (Cap, Suit, Shield). I guess they have another use other than looking cool afterall ;D
Yep I did that run from start of T3 to basil and got good mats like that and also 2 ghost bells.
