Whether by magic or a curse of your blood, some part of you is more beast than man.
Prerequisite: Beast shape class feature.
Your bestial nature manifests itself in one of the following ways. You choose the manifestation when you choose the feat, and then you cannot change it.
Night Senses (Ex): If your base race has normal vision, you gain low-light vision. If your base race has low-light vision, you gain darkvision out to a range of 30 feet. If your base race has darkvision, the range of your darkvision increases by 30 feet.
Claws of the Beast (Ex): You grow a pair of claws. These claws are primary attacks that deal 1d4 points of damage (1d3 if you are Small). If your beast shape already has claws, then it improves by 1 size larger (1d6 medium, 1d4 small, for example).
Predator’s Leap (Ex): You can make a running jump without needing to run 10 feet before you jump.
Wild Instinct (Ex): You gain a +2 bonus on initiative checks and a +2 bonus on Survival skill checks.
