Rage Rules
From KJD-IMC Wiki
Some characters can enter a savage fury when fighting that gives them certain advantages. This savage fury is referred to as 'raging'.
A character who can rage can activate it as a free action on his own turn. He cannot do so on another character's turn, nor may he do so if unconscious. A character may only rage once per encounter and only a limited number of times per day.
When raging, a character gets a +4 bonus to Strength, a +4 bonus to Constitution, a +2 morale bonus to Will saves, but suffers a -2 penalty to armor class. The bonuses has the normal effects (including improving Fortitude saves and increasing hit points). Increased hit points are not temporary hit points; they are not lost first as hit points from some spells.
While raging, a character cannot use skills or abilities that require patience and concentration. Spellcasting is precluded while raging. Combat Expertise cannot be used while raging, but other feats in the Expertise tree are still available.
Raging lasts for a base of three rounds plus one round per point of modified Constitution bonus. The character may choose to end his rage earlier but still suffers the post-rage fatigue.
After raging, the character loses all bonuses gained from the rage and is fatigued (-2 penalty to Strength, -2 penalty to Dexterity, and cannot run or charge) for the remainder of the encounter. All hit points gained from the increased Constitution are immediately lost.
