Damage Reduction
Feats
At 10th level, a mad dog gains damage reduction. Subtract 1 from the damage she takes each time she is dealt damage from a weapon or a natural attack. At 13th level and every 3 levels thereafter, this damage reduction rises by 1, to a maximum of DR 4/— at 19th level. Damage reduction can reduce damage to 0 but not below 0. A mad dog's war beast gains the same damage reduction as the mad dog.
