@KnuckleBrown: dark metamorphosis deals out a pretty large amount of damage over time when we're in close using demon impact.
while to a lesser extent, Cerberus and demon cry is used often enough too through a boss fight where crit would be beneficial for this too.

[quote=chickenpoodl]in my books, the phantom's 10/15/20% crit rate is probably more important than the others.
in a real close second, it'll probably be the Cygnus knight 5% (at lv120) status resists (you can get 100% status resist a lot eaiser when you have these done)
beast tamer's (at 120), 7% boss, 7% crit rate, 4% hp/mp might be the best after those (all because of the crit rate, once again)
kanna or demon avenger's 10% total dmg, xenon's 10% allstat, luminous 10% def ignore, comes next.
last would be jett, cannoneer, hayato, I suppose, for those raw stats.[/quote]

I thought demon impact made crit rate kinda irrelevant. Unless you mean getting it to help with 100% crit for endgame training with demon cry, in which case I would agree with you under those terms.

1/2) Kanna and Demon Slayer.
3/4) Beast Tamer and Phantom
5) Luminous.
6/7)Jett Hayato

Xenon for 10% allstat.
Mercedes is not worth it i.m.o.
It's not the most important.

1.mercedes for leveling
2.demon avenger for damage
