You've made a thief class in a Final Fantasy game... And haven't included steal. That's their signature ability!

Other than that, there's some really cool and unique stuff here. Boosting damage under certain conditions (like low enemy health or being based off enmity) is something I'd really like to see. Trick Attack which is essentially a reverse Collusion is also pretty sweet.

Some of these skills are way too OP though. In particular, Enchanced Time Bomb sounds like it would devestate large groups and Rogue's Rancor is just ridiculous, being able to pass all your enmity is too much.
