Soo... Sneak Attack(?)

[Lillia]

Sneak Attack and Trick Attack are moves that can only be used under the effect of Hide (which can't be activated in combat) or Suiton (Ninjutsu).
For smaller scale content like 4 man dungeons or solo play, Sneak Attack will be the skill of choice, for raids, Trick Attack will be, because;
1. It's infinitely safer to do
2. the 10% damage increase for 10 seconds is awesome.

Yeah, a friend pointed that out. ^^ sorry!
