[3.5]Improved monster classes: adapting creatures for player use-taking requests!

[Mystic Muse]

Hmm. Looking at the Anathema there are a few problems. There aren't really enough abilities to spread out across 18 levels. It has a couple SLAs, Constrict, poison, two immunities, two extra movement modes and a couple resistances. That's about it. As is, you could use the Yu-anti, give it two growths at certain HD, reflavor it and call it a day.

I'm going to look for something else that's a bit more unique.

EDIT: The Policy is The amount of levels is equal to the CR of the creature correct?
