Pain Mastery

(Savage Species, page 37, DnD 3.0)

[General]

Injuries send you into a fury, increasing your physical power.

Prerequisite

Toughness, CON 20

Benefit

You take damage normally, but every 50 points of damage you take (if you survive the attack) automatically increases your Strength by +2. This bonus lasts until the end of the encounter, after which you are exhausted. See the Condition Summary in Chapter 3 of the DUNGEON MASTER's Guide for the effects of being exhausted.
