Your mastery of shapeshifting magic allows you to reshape your flesh in small but significant ways.
Prerequisite: Ability to cast 4th-level spells.
Benefit: As long as you have a polymorph spell of 4th level or higher available to cast, you can spend a swift action to grant yourself one of the following benefits:
Might: +2 bonus on melee damage rolls.
Mobility: +2 competence bonus on Balance, Climb, Jump, and Swim checks.
Savagery: Primary claw attack dealing 1d6 points of damage (assuming Medium size).
Speed: +5-foot enhancement bonus to any one movement mode you already possess.
Vigor: Temporary hit points equal to your HD.
The chosen benefit lasts for a number of rounds equal to the level of the highest-level polymorph spell you have available to cast. If you activate this feat a second time while a previous benefit is still in effect, the first benefit ends immediately.
As a secondary benefit, you gain a +1 competence bonus to your caster level when casting polymorph spells.
