True Dragon's Soul

Heroic Tier
Prerequisite: Dragonborn, sorcerer, Dragon Magic class feature
Benefit: The first time you become bloodied during an encounter, you gain a +1 bonus to Fortitude, Reflex, and Will until the end of the encounter.
If your breath weapon deals the same type of damage as the resistance granted by your Dragon Soul, your breath weapon ignores all targets' resistance to that damage type up to the value of your resistance.
