Cobalt Plateaus - 8

Difficulty
5. Considerably hard

Strategy

 * 1) Buy Red's Guardian class (and if possible, Chuck's Lightning Bird class).
 * 2) Defeat the 2 Stick Pigs. Make sure to use Red's secondary skill when the Pryopig is about to attack if it has expired. Use Chuck's secondary skill to Red or himself (but not on Chuck himself when he is Lightning Bird).
 * 3) Repeat step 2 over until the Rage Chili is full, use it on Red or Chuck.
