last I heard it was a level based success rate like parfait said and it applies to players aswell seeing how they're demi human.. but the duration of wink of charm is... well its awful lol so I wouldn't bother

The skill will fail on high level monsters and boss monsters. If used on a player, it will have a low chance to cause the Chaos status ailment.
Charming Wink only works on Demon, Angel, and Demi Human type monsters.
