[And the weird thing for Zelgadis isn't the lack of magic. It's that he's realized that he had gotten used to treating his chimera body as proper armor, and doesn't know if the fact he is a lot easier to damage or that 'getting hit by a sword can hurt' seems weird to him.]

[Oh, well, set the extitentialism about Zelgadis's condition on the back burner (where it has a comfortable home) and focus on the task at hand]
