Monsterous races
Athas is known for various powerful races, some of which were intended as player selections. In general, as a rule of thumb subject to modifcation in edge cases, a monster is a character of it's CR+1. For the base races (with modifications) it comes out as this:
Aakerocera: 1HD monsterous humanoid. You can fucking fly, you can deal with shitty statmods and a racial HD.
Thri-Kreen: 2 HD monsterous humanoid.
Half-Giant: 2 HD giant, stat mods changed to +8 Str, -2 dex, +4 con, -2 int, -2 wis, -4 cha.
Mul: +0. Enjoy the strength. They don't actually get many benefits besides that.
Other races that may be intresting
Gith: +0
Nikall: +0
Bvanen: 3 Abberation Hitdice
Dray (both): 1 dragon hitdie
All characters may have on "regional" feat from the list in the book, with the exception of Freedom, which is banned. If you'd rather have a similar, non effective pre-requesite feat for this slot, such as..dodge or the like, feel free.
