Greater Rage

Type of Feat: Class
Prerequisite: Barbarian.
Specifics: The barbarian may rage, gaining a +4 morale bonus to Strength and Constitution and +2 to all Will saving throws, in exchange for a -2 penalty to Armor Class. The barbarian may use this ability once per day at first level, +1 use per day at level 4, and every 4 levels thereafter, extending into epic levels.
Use: Selected. At 15th level, the rage ability becomes greater rage, giving the barbarian +6 to Strength and Consitution and +3 to Will saves (the -2 penalty to Armor Class still applies).
