Moonlight Mercy's 'special effect' for PvP is to give +24 flat critical damage to all weapons, so go figure. It's a very good weapon at the moment, and if you're lucky, you can make a bloodbath in a Crazy dungeon after a Lead Storm.

But I do think this special effect, for being so specific, shouldn't just be applied 'if' the enemy NPC is under fear. If we remove the fear from the condition, it might make this weapon more worth for PvE, if that's what you're trying to say.
