I loathe and despise Disarm.
Fear and Calm are also epically useless.
Calm has'nt worked once any of the rare times I used it. It just made them angry.
I tried using a staff of calm on a sleeping Heimskr and he woke up and attacked me.
That's just stupid.
Bound weapons are also useless. You may as well hit them with nothing.
Too weak to fight with, and they're only use is for when there is disarm using enemies about.
Who are so big, they laugh at the summoned weapons, that do no damage to them.
Duel weilded magic is better and hell of a lot more effective.
