Another small idea, this one doesn't have as much thought put in for which class it would go to, but my vote is Bonder. A skill that allows for half of the elemental attack of the damage type the youkai's basics uses to go into additional damage for it. (if it's blunt pierce or slash then default strength/fire elemental attack). I say it'd be interesting on Bonder as it would actually encourage the use of basic attacks on youkai since Bonder does have bonuses to hit crit and evade already.
