Social creatures instinctively avoid aggressive posturing in the presence of more dominant leaders. You have learned the ability to enforce this respect, forcing others to revert to their natural form.  

Amalgam: Presence 2

Cost: Two Rouse checks

Challenge Pool: Strength + Survival vs. Composure + Resolve

System: Make two Rouse checks, spend your standard action, roleplay a show of dominance (a roar, a vicious glare, or other predatory gesture) toward a target in your line of sight, and make an opposed challenge using your Strength + Survival vs. the target’s Composure + Resolve. If successful, you force your target to immediately return to her natural form. Further, she cannot use transformative powers for the next hour.

Shape Mastery ends the effects of a transformative power, such as Shape Change and Horrid Form. It also ends the natural shape-changing ability of other supernatural creatures such as werewolves. It cannot affect powers that alter only a small portion of the body, such as Feral Weapons, or powers that alter the body but are not transformative, such as Earth Meld.

Duration: One hour
