Vigorous training and conditioning exercises have toughened your mind and body considerably, allowing you to shrug off most blows.

When you take bludgeoning, piercing, or slashing damage from a nonmagical source, you can use your reaction to absorb a portion of the blow, reducing the damage by half. You can use this ability a number of times equal to 1 + your Constitution modifier (minimum once). You regain all uses of this feat when you finish a long rest.
