Patch: Tespia 1.2.190

I think the biggest problem with Zerk is that it doesn't play out too well in a game where your HP can go from 20k to 1 and back several hundred times in the course of a boss fight. The idea of being stronger at low HP works well in other games, but in MapleStory it basically forces Dark Knights to do whatever they can to stay in Berserk mode. Dark Knights come to hate being healed, which makes no sense.
