:P

@Echoez:
No proof whatsoever, going based off of my experience/personal judgement of Khorovod vs. Avenger, I could just have sworn that the Khoro's arc was wider at the sides (as in, hit mobs farther to your sides, whereas the other needed mobs to be closer in front of you), however the DA seems to be catching the same mobs as Khoro now, so either the DA has an equal hitbox, or it's just my imagination entirely. I think I addressed that earlier, (may not have e.e) but I don't blame you for not readin' all these megas.
I can't remember where that was said at all, but if it was hidden somewhere in the OP I'll try look for it and remove/reword it to keep accurate.

When the Sudaruska came out, I was happy to see that there was something to balance out the weaker/normal damage - that its range was greater than DA/GF.
After extensive testing, I found out they have the same exact hitbox, and that DA/GF/SS all have hitboxes that extend further than their graphic.

Q2: Aye, never had any problems with that myself. My Khoro is +10 ofc, but no other CTR bonuses. If the Suda's charge is longer then I couldn't say, but the Khoro can get in with some very slightly time to spare, assuming you pre-switch and start charging before the vortex det's. Haven't actually tried it with the DA yet as the projectiles are more awkward to fit into the crowd, and the main damage swing involves you being in their faces; I like the Khoro charge for vortexes becasue it lets me stand beack and hit, but this is also because I tend to do this to mobs that hit me hard, such as Mech Knights, Lumbers etc, on the basis that my shield might as well be my forehead for all the good it does against those guys.
@ bolded: You can lay down the DA's projectile at swing range and it'll work, pretty sure. That aside, if you tend to charge attack vs mechas and lumbers, you deal more damage to them using DA- whether you're swinging or charging 9_9;

i can use triglav instead of suda?

that the 2nd swing dinnae ( ;p ) freeze anymore? Cuz the suda dinnae ( ;p [again]) stun anymore.

@OP: I love the idea of this build. However, I'd think that a somewhat more mobile gun would be more useful. I use a similar build, but i'm only in t2, with 3* items. I mainly use the Kamarin, and I love it. I can't wait to make it into a Sudaruska. Anyway back on topic, I use a firotech alchemer, and I think that it complements the slow sword style nicely. It deals elemental, which is effective against 2 out of 3 of the tower types, which are the main thing a swordsman would be using his gun on, and is neutral against polyps. Either way it deals good damage, you still have mobility while using it, and the fire status effect is, as you said, great for adding a little consistent damage. I don't know how the magma driver stacks up against the volcanic pepperbox, but I know that I prefer the alchemer's dynamics hands down over those of the autogun.

a nice way to avoid being hit after the second swing freeze would simply be attacking the monster from behind, or the sides, speciall for darkfang thwackers (although it sucks for mecha knights and giant lichen colonies when they charge). as for the charge attack, do it from a nice distance, or from the side/back too.

I hate reminding people this, it's so depressing.

A an avid pepperbox user myself I can confirm that there is no "anti-knockback" that goes with the pepperbox.

Instead you have to run up to enemies with the charge, and when the guns sprite is right up in their face, you release it so that almost every bullet in the charge (two or three might miss) goes and delivers it's fiery payload and knocks them back.

By the way, normal attack is pretty good but it has no knockback whatsoever.

P.S. I've been planing to update the gunning guide on the wiki with his but I just haven't got around to it.

@Darkbrady: you mentioned that your Khorovod does more net damage than the Acheron due to hitting several targets for high damage, and implied that the knockback makes it safer. You only compared it to the Acheron's normal swings, but you forgot what makes them famous - their charges. I've used my Acheron to OHKO whole packs of Gremlins and still had time and distance to do it again. It offers much the same safety as Khorovod for much higher damage.
