It's 90% for most spells, excluding serpent bite, because that's special and its DoT can only be lowered by more than 85% with the use of strategic position. Why? Who knows. /shrug

And the Dark Archmage tunic has been bugged for as long as I can remember. It provides more AP than the skull tunic, and the winged death tunic and every other tunic I've worn on my lock.
