Instructions
Transform into either Swampfire or Spidermonkey at the beginning of the battle. Both are fast-moving, which is helpful for this battle. Swampfire is particularly useful because of his projectile attacks.
Kill the Rock Monsters that Charmcaster summons at the beginning of the battle. Avoid close combat because they tend to swarm you, making it difficult to avoid their attacks. The Rock Monsters don't deal too much damage but if you are surrounded, there is a good chance you will lose the battle.
Transform into Humungousaur and walk up to the pillar where Charmcaster is sitting and interact with it to grab the ring and rip the pillar down. Transform back into either Spidermonkey or Swampfire and start attacking her at close range.
Block against Charmcaster's attacks. She takes a while to charge them up, so you can tell when you need to block. Once her attack is over, start attacking her again. Eventually, she teleports to a different pillar and summons more Rock Monsters. After this round of Rock Monsters, Charmcaster makes parts of the floor move, which creates pitfalls into lakes of lava.
Transform into Big Chill whenever you need to jump over large chasms in the floor -- his glide ability is helpful for moving around the field. At this point in the battle, the floor will be constantly changing, so pay attention to where you are going so you don't fall. Repeat the process of killing the Rock Monsters, tearing the pillars down and attacking Charmcaster until you have defeated her.
