This... is interesting lol

She surely is worse than Phantom and Benkei, to the point she is broken in the worst way possible: Low damage boost, a lot of self-debuffs, low stun chance... That makes her passives (24% perma Buster up is good!) and the defense down on her NP the only good part about her. Congratulations, you made her so bad nobody would ever attempt to use her lol (I say that, but there ARE people who would)

Now, for some tweaks that would still make her underwhelming but still playable: 1st skill: Increases damage to 20%. On a selfish, 1-turn deal, it's still bleh. 2nd skill: increase the seal chance by 20%. Slightly more reliable but still shit. 3rd skill: make it a 50% defense up instead, and make the On-Death effects enemy-only debuffs. That way, it's harder to kill her despite the taunt BUT the effect are still decent if it connects.

I assure you that even with those upgrades, she would still be worse than Phantom and Benkei (who are still decent at crippling the enemy, all things considered).
