Bishop Damage Equal to Archmage Damage

I'll test again on some other mobs tomorrow, but I ran down a Kacchuu Musha and an Anego today and their DoT values were too similar to account for any kind of bonus on the ice-weak Kacchuu Musha. Oh well, more testing tomorrow then and I was obviously not Elemental Reseting on the two lightning-weak mobs.

It might have to do with Ice Demon itself not being able to. It should show its neutral damage when you attack once, and if you use it again, it should show increased damage since the monster's ice resist was lowered. I know for sure Poison DoTs are affected by weaknesses and advantages.
