d20 Modern refuses feats to creatures of the animal type. Everything else gets feats normally, though...hm.
It does? That would explain it then. I thought the feat rules were basically the same as 3.0. I never bothered reading the rules very closely, never having played it.
Anyhow, getting back to our 3.5 chimp, what are we doing skills & feat wise.
So far we've got:
Alertness and +10 Climb, +4 Listen, +4 Spot, +4 Survival, -2* Swim
Improved Grapple and +10 Climb, +3 Listen, +3 Spot, +2 Survival, -2* Swim
Alertness and +10 Climb, +4 Listen, +4 Spot, +4 Survival, -2* Swim plus giving it Improved Grab and Rend as special attacks.
They all work for me, so which do you fancy?
