Description: Take massive damage, rage until the end of combat

Prerequisites: Toughness, CON 20

If you survive 50 points of damage from a single attack and make your Fortitude save (see Massive Damage), on your next action you gain +4 to Strength, +4 to Constitution, and -2 to Armor Class. These adjustments last until the end of the combat, at which time you become fatigued. For details on being fatigued, see the Condition Summary in DnD 3.6e tutorial.
