Stacking Up

Stacking Up is one of the Challenges available in The Arena.

Description
"It's not enough to win, you know... sometimes, you need to win big. We had a guy in here once... defeat about a million wisps in an afternoon. Think you can come close..?"

Strategy
Keep using Inspire to boost your damage, and hit the enemies with super-effective or normally-effective attacks, so you either do more damage or you never do less damage respectively. Take the Overcast mechanic into account as well, especially for Wade's Attack and Gwen's Bash.
