I'm doing the Quest Bloodworm Helm for the Arch Mage Traven and I'm really stuck.
I'm level 18 and I have to defeat 2 Daedroths. My magic weapon Sufferthorn does 10 damage and my most powerful spell only does 15 damage as I cant cast Wizards Fury because I don't have 50 Destruction points.
How can I kill them?

P.S. I dont have to kill them at the same time.
