soul trap for 1 second + 15 fire damage, 30 shock damage. deadric, legendary all that good stuff. with enchantments etc i think it does 217 damage + effects.
EDIT: my mistake, 10 fire damage rather than 15 and 20 shock rather than 30
there is an enchantment (cannot remember the name) that has soul trap + fire damage and it counts as one enchantment and uses the charge of 1 enchantment but with 2 variables.
Mines the same as OP, but without enchantments (which i think ruins weapons and armor) But i hate instantly killing Scourages with one shot, so i only use it for things like Ancients Dragons and Priests.
