Are there level adjustments anywhere for the Tome of Horrors? I am running a campaign centered on Fey, and Atomies, Brownies, Buckawn, and Leprechauns all look as viable as the sprites in the MM.
This might not be what you're looking for, but presumably the Tome of Horrors 3.5e update that's coming out soon will have those in. Doesn't help those of us with the 3.0e version thought.
