If you would like to play a Centaur character the following changes are in effect:
1.The centaur loses its racial HD
2.The centaur loses its feats, base attack bonus and save bonuses conferred from its racial HD
3.A centaur is treated as if it was a mounted warrior and may take feats related to mounted combat
4.A centaur is treated as if it had the mounted combat feat for feats that require it as a prerequisite
5.A centaur may take ranks in acrobatics instead of ride to qualify for mounted combat related feats.
