I have created a skeleton boss and want it to dual wield flames left hand and drain health right hand. I have gave him a destruction skill of 100 and have tried various encounter classes and AI Combat Styles:

EncClass draugrmagic, CombatMage, csdraugrmagic, csdraugrmagicallowdual, csmage etc.

When my boss goes into combat he just raises both his hands but does not equip the spells. he just runs around with his hands raised. any help please???
