Blood Pool

Feats

At 2nd level, a bloodseeker gains a blood pool of points which he can use to amplify his powers and use supernatural abilities. The blood pool contains 2 points at 2nd level and increases by an additional point for each level thereafter. The pool is replenished after resting. The DCs of blood pool abilities are equal to 10 + the bloodseeker's level + his Intelligence modifier.
