Rage (Ex)
A barbarian can call upon inner reserves of strength and ferocity, granting her additional combat prowess. Starting at 1st level, a barbarian can rage for a number of rounds per day equal to 4 + her Constitution modifier. At each level after 1st, she can rage for 2 additional rounds. Temporary increases to Constitution, such as those gained from rage and spells like bear's endurance, do not increase the total number of rounds that a barbarian can rage per day. A barbarian can enter rage as a free action. The total number of rounds of rage per day is renewed after resting for 8 hours, although these hours do not need to be consecutive.
While in rage, a barbarian gains a +4 morale bonus to her Strength and Constitution, as well as a +2 morale bonus on Will saves. In addition, she takes a –2 penalty to Armor Class. The increase to Constitution grants the barbarian 2 hit points per Hit Dice, but these disappear when the rage ends and are not lost first like temporary hit points. While in rage, a barbarian cannot use any Charisma-, Dexterity-, or Intelligence-based skills (except Acrobatics, Fly, Intimidate, and Ride) or any ability that requires patience or concentration.
A barbarian can end her rage as a free action and is fatigued after rage for a number of rounds equal to 2 times the number of rounds spent in the rage. A barbarian cannot enter a new rage while fatigued or exhausted but can otherwise enter rage multiple times during a single encounter or combat. If a barbarian falls unconscious, her rage immediately ends, placing her in peril of death.
Controlled Rage (Ex)
When an urban barbarian rages, instead of making a normal rage she may apply a +4 morale bonus to her Strength, Dexterity, or Constitution. This bonus increases to +6 when she gains greater rage and +8 when she gains mighty rage. She may apply the full bonus to one ability score or may split the bonus between several scores in increments of +2. When using a controlled rage, an urban barbarian gains no bonus on Will saves, takes no penalties to AC, and can still use Intelligence-, Dexterity-, and Charisma-based skills. This ability otherwise follows the normal rules for rage
Weapon and Armor Proficiency
An urban barbarian is not proficient with medium armor.
Skills
An urban barbarian does not gain Handle Animal (Cha), Knowledge (nature) (Int), or Survival (Wis) as class skills; instead, she gains Diplomacy (Cha), Knowledge (local) (Int), Knowledge (nobility) (Int), Linguistics (Int), and Profession (Wis) as class skills.
Crowd Control (Ex)
At 1st level, an urban barbarian gains a +1 bonus on attack rolls and a +1 dodge bonus to AC when adjacent to two or more enemies. In addition, her movement is not impeded by crowds, and she gains a bonus equal to 1/2 her barbarian level on Intimidate checks to influence crowds.
This ability replaces fast movement.
Invulnerability (Ex)
At 2nd level, the invulnerable rager gains DR/— equal to half her barbarian level. This damage reduction is doubled against nonlethal damage.
This ability replaces uncanny dodge, improved uncanny dodge, and damage reduction.
