Furious Transformation (Su)
Replaces: Improved Uncanny Dodge
At 5th level, a rageshaper can attempt to bolster any transmutation spell from the polymorph subschool on the bloodrager spell list while bloodraging. The rageshaper must succeed at a concentration check as if casting defensively to modify the spell; otherwise, the spell is wasted. If he succeeds, the spell is treated as if the rageshaper had the Extend Spell metamagic feat. The rageshaper must be the spell’s intended target or must cast a spell with a range of personal to gain this effect. If the rageshaper casts a spell that is associated with his own bloodline, such as a rageshaper with the elemental bloodline who casts elemental body I, the spell is automatically extended without forcing the concentration check, so long as the rageshaper casts it while in a bloodrage. This ability replaces improved uncanny dodge.
