@Owyn so you're saying the tags have TWO flaws?
Also i haven't read the wn but i think i kinda knew how his Accursed Evil Eye works (a theory). Basically super effective to foes who had many grudges against them. Using the accumulated grudges to attack their minds directly (hence why no blood flowing out).
[Accursed Evil Eye]
This skill is active as long as the user has a heavy grudge against foe. While active, user emits dreadful aura that slows speed of all foes's in range. Applies [Cursed] status to foe and reduces foe's willpower and max HP by X every 10 second (X = the number of people who has a grudge against foe).
