two v. two v. two v. two v. two (full)

[Zooko]

Um, I hate to sound like a confused newbie, but could anyone explain why all of my troops which attacked the Medusa disappeared instantly? She didn't have a longer weapon, so she couldn't have repelled them, right? And she didn't have a Fire Shield or such. She did have a Charged Body, but that should have (a) included her taking a hit, (b) made a sound and light show, (c) killed only the first attacker, not all of them.

Please help, as it doesn't seem like much fun to try fighting her again at this point...
