Constitution Rerolls: Spend a Harrow Point to reroll any one Fortitude save, or other Constitution-based d20 roll. You must abide by the new result (although if you have additional Haroow Points remaining, you can use them to attempt additional rerolls).
Fast Hit Point Recovery: Spend a Harrow Point after resting for a minute to catch your breath and recover from your recent ordeals - you heal a number of HP equal to your class level and 1 ability point of damage (but not ability drain) each time you do so. You may spend a Harrow Point in this manner once after each encounter.
Damage Reduction: Spend a Harrow Point to gain DR 3/-. This DR persists for the duration of the encounter in which you spent the Harrow Point.
