Arena 101

Arena 101 is one of the Challenges available in The Arena.

Description
"You're comfy with all the basic heroes' powers now, right? At least a little? Grandmaster'd like a little proof from you. Prove you can take these vile goons and survive."

Strategy
Shouldn't be too hard since you only have 8 abilities to choose from at any given point of time. Use appropriate elemental attacks where possible, but above all, make sure your health is in good shape with Cure.
