Some Bracing Impacts

Some Bracing Impacts is one of the Challenges available in The Arena.

Description
"Okay, so that last idea was terrible. Let's do the opposite, maybe? How much damage can you pour out before this song ends? A bunch, I bet!"

Strategy
Even allowing for attacks that aren't type-effective (except for same-type attacks that are less effective), this shouldn't be much of a problem. Just remember to keep your health at a safe level.
