Hmm would Axii work on a Golem? Never tried but for the Arena I found the talent that increases the distance traveled when rolling by 200% incredibly useful. It allowed me to get passed the Golems, 4 (or 5?) werewolves and easily handle the Draugh and Draughirs.
Also with Quen at 2/2 and Venting at 2/2 it can make quick work of a lot of the things you'll encounter in the Arena.
