Benefit
Your massive damage threshold increases by 2 × the number of Monstrous Blood feats you possess, and you add your bloodline level to the number of negative hit points you can accrue before dying. Bleed damage you take to hit points is reduced by 1/2 the number of Monstrous Blood feats you possess.
In addition, you gain a bonus on saves against disease and poison equal to the number of Monstrous Blood feats you possess.
