You become one with the creature you ride into battle.
Prerequisite: Animal Companion class feature, Mounted Combat, wis 13
Benefit: While riding your animal companion, you may use any of the following senses if possessed by your animal companion: darkvision, low-light vision, and scent. Also, if your animal companion has a racial bonus to Perception, you gain a +2 circumstance bonus to that skill as well.
I want there to be reasons to ride your animal companion around other than taking mounted feats for extra charge damage.
