Holy - 2x damage vs. Undead
Arcane - 2x damage vs. Deamons
Fire/Poison - 4x weapon damage over XX seconds (DOT)
Lightning - 1.5 second stun on hit.
I mean, if Cold gets an auto SLOW hit, shouldn't the others get something like the above? Or am I missing something and the other elemental damages have an effect I'm not aware of??
