I'd see the Mark of Retaliation spell on Lucy before, as it's listed as a Cleric spell, but I've certainly never seen it in game...until now. It's just like Mark of Retribution, only this one is a 35 point damage shield. *Very* nice.
Since the recent patch you almost need 200+ resists. I just love getting chain nuked by green casters 20 levels lower than me and having EVERY spell land. Thanks Verant
