You should've placed some limits on his Chaos Magic beforehand, but sonce you haven't done that, lets put it like this: teleportation is a spell powerful enough to have a mention of its own. IMHO, any power that goes farther than shooting moderately fast and powerful stuff at your foe has to be described.

Morever, you only mentioned him being able to [i]sling magic out of his axe[/i], which most likely implies offensive use of magic.
