All good. Updated.
Added to Homebrews.
Since it had rake, I gate it improved grab and pounce to go with it, like many other big cats. Should we reduce the base speed and drop sprint, since it was only said to resemble a cheetah, not necessarily possess its speed?
Since its "sphere is filled with jagged rocks and a pool of mud", perhaps a 20 ft. climb speed like a leopard? Maybe some Swim ranks like a tiger?
Ah, well then the eyewing can probably wait a bit.
Cheetah is Str 16, Dex 19, Con 15, Int 2, Wis 12, Cha 6. Fiendish does nothing much to abilities, while half-fiend does Str +4, Dex +4, Con +2, Int +4, Cha +2. How about Str 20, Dex 21, Con 17, Int 2, Wis 12, Cha 8?
