Fast Movement (Ex): A barbarian's base speed is faster than the norm for her race by 10 feet. This benefit applies only when she is wearing no armor, light armor, or medium armor, and not carrying a heavy load. Apply this bonus before modifying the barbarian's speed because of any load carried or armor worn. This bonus stacks with any other bonuses to the barbarian's base speed.
18/Day
Rage (Ex): A barbarian can call upon inner reserves of strength and ferocity, granting her additional combat prowess. At 1st level, a barbarian can rage for a number of rounds per day equal to 4 + her Constitution modifier. For each level after 1st she possesses, the barbarian can rage for 2 additional rounds per day. Temporary increases to Constitution, such as that gained from bear's endurance, do not increase the total number of rounds that a barbarian can rage per day. A barbarian can enter a rage as a free action. The total number of rounds of rage per day is renewed after resting for 8 hours, although these hours need not be consecutive.
While in a rage, a barbarian gains a +2 bonus on melee attack rolls, melee damage rolls, thrown weapon damage rolls, and Will saving throws. In addition, she takes a –2 penalty to Armor Class. She also gains 2 temporary hit points per Hit Die. These temporary hit points are lost first when a character takes damage, disappear when the rage ends, and are not replenished if the barbarian enters a rage again within 1 minute of her previous rage. While in a rage, a barbarian cannot use any Charisma-, Dexterity-, or Intelligence-based skill (except Acrobatics, Fly, Intimidate, and Ride) or any ability that requires patience or concentration (such as spellcasting).
A barbarian can end her rage as a free action, and is fatigued for 1 minute after a rage ends. A barbarian can't enter a new rage while fatigued or exhausted, but can otherwise enter a rage multiple times per day. If a barbarian falls unconscious, her rage immediately ends.
Rage powers
Knockdown Stance (Ex): The barbarian can focus on toppling her foes. Once per round, she can make a trip attack against one target in place of a melee attack. If she succeeds, the target is knocked prone. This trip attempt doesn't provoke an attack of opportunity. This is a stance rage power.
No Escape (Ex): The barbarian can move up to double her base speed as an immediate action. She can use this ability only when an adjacent foe uses a withdraw action to move away from her. She must end her movement adjacent to the enemy that used the withdraw action. The barbarian provokes attacks of opportunity as normal during this movement.
Uncanny Dodge (Ex): At 2nd level, a barbarian gains the ability to react to danger before her senses would normally allow her to do so. She cannot be caught flat-footed, nor does she lose her Dexterity bonus to AC if immobilized. A barbarian with this ability can still lose her Dexterity bonus to AC if an opponent successfully uses the feint action against her.
If a barbarian already has uncanny dodge from a different class, she automatically gains improved uncanny dodge (see below) instead.
Danger Sense (Ex): At 3rd level, a barbarian gains a +1 bonus on Reflex saves to avoid traps and a +1 dodge bonus to AC against attacks by traps. In addition, she gains a +1 bonus on Perception checks to avoid being surprised by a foe. These bonuses increase by 1 every 3 levels thereafter (to a maximum of +6 at 18th level). This ability counts as trap sense for any feat or class prerequisite, and can be replaced by any archetype class feature that replaces trap sense. The bonuses gained from this ability stack with those gained from trap sense (if the barbarian has trap sense from another class).
