Level 1
As a move action, you can grant yourself DR 1/— for a number of rounds equal to your Strength or Constitution modifier (whichever is higher; minimum 1 round). Once you have used this ability, you can use it again only after you take a 10-minute rest to regain Stamina Points. This DR increases to DR 2/— at 5th level, DR 3/— at 9th level, DR 4/— at 13th level, and DR 5/— at 17th level. If you have DR from any other sources, the DR you gain from this ability increases by 1. Each time you are attacked while this ability is active, you can use either this DR or the DR gained from another source.
