[hider=Yuto]There's an NPC that uses Iaijutsu style of fighting, which is what your abilities is reminiscent to. That might occur some interest. Just keep in mind what your ability cooldowns and durations will be, I'm more than happy to help in this department if need be.

Is there a limit to how much spirit energy is accumulated or is it ever growing? Either or is fine, just want clarification.[/hider]

There is a limit, it is roughly twice his strenght, conceptually the boost is proportional to his own strenght.
