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 AC. The Barbarian may use this ability 1x/day at 1st level, +1/day at 4th level, 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 Constitution and +3 to Will saves (the -2 penalty to AC still applies).
Bow changes
Barbarian Rage: Provides additional bonuses of +1 Attack Bonus, +1 Damage, +1 Fortitude, +1 Discipline, and +1 Concentration. Succeeding a difficulty check of Constitution modifier + 1d20 vs. DC 21 will halve the -2 AC penalty. The unraged Constitution modifier is doubled in the duration calculation.
Greater Rage: Instead of increasing Strength and Constitution 6 points, the increase is only 4 points. However, it provides additional bonuses of +2 Attack Bonus, +2 Damage, +2 Fortitude, +2 Discipline, +2 Concentration, and 1 HP per character level. Succeeding a difficulty check of Constitution modifier + 1d20 vs. DC 21 will halve the -2 AC penalty. The unraged Constitution modifier is tripled in the duration calculation.
The following spells and feats are weakened when used together: Divine Favor, Divine Power, Divine Shield, Bard Song (level 12+), Barbarian Rage, Greater Rage, and Mighty Rage. The first one used is at full power but any subsequent are half power, but Divine Favor is simply removed when Divine Power or Rage is used. Divine Shield's duration is unchanged.
