Wink of Charm is its own status effect where the monsters it can be cast on make a heart emoticon and walk around like doofuses till you hit them with a skill or attack or the duration of the skill ends.
Its actually quite a useful skill despite some of its limitations, there is a reason I started playing around with an aliza orleans uniform in the first place. I think the use of it isn't for pvp anyway but I admit confusion actually is frustrating if you ever have it happen to you heh.
