Skyrim : does “Two-handed attacks do 13% more damage” apply to dual casting spells, or just melee weapons?

Question

It is unclear to me if "Two-handed attacks do 13% more damage" apply to dual casting spells, or just melee weapons? because basically dual cast is a two-handed attack. please help

Answer 1

It applies only to attacks with two-handed melee weapons.

If it helps, reread the language as attacks based on your 'two-handed weapon' skill do 13% more damage.

And before you ask, yes, that means it doesn't apply to bows either.

Answer 2

No. Two-Handed attack bonuses only apply to attacks with a two-handed melee weapon.

Answer 3

No. That bonus doesn't apply to bows or duel casting spells. It pertains to the Two-handed weapon skill weapons only.
