Beast Shifting

Wild shift class feature, Base Attack Bonus +3

When you use your wild shift ability, you may choose to take on the traits of greater beasts and magical beasts. You have access to the following additional wild shift options.

Behir Grab: You gain a +4 bonus on grapple checks and a Constrict special attack, which deals damage equal to 1d8 + your Strength mod.
Bulette Delve: You gain a burrow speed equal to 1/4 your land speed (minimum 5 feet). While burrowing, you gain tremorsense out to 30 feet.
Hydra Flesh: You gain Fast Healing 1, but this healing can only heal you to a maximum of one-half your normal hit points.
Trample: When you successfully Overrun an opponent, you may use a free action to make a Trample attack against that opponent which deals damage equal to 1d8 + twice your Strength mod.
Venomous: Your bite attack allows you to deliver a potent venom which deals initial damage of 1d2 Con and secondary damage of 1d4 Con (Fort DC 10 + 1/2 your class levels that grant wild shift + your Con modifier). You must already have a bite attack to activate this wild shift and can use this venom only once per minute.

A moreau cannot gain the benefit of this feat with only her racial wild shift ability, because the moreau racial wild shift ability can only be used for their racial wild shift. A moreau may gain this feat is she has wild shift from another source which allows more than just her racial wild shift and may spend any of her wild shift uses (even her racial ones) to activate it.
