As a barbarian gains levels, she learns to use her rage in new ways. A barbarian gains the benefits of rage powers only while raging, and some of these powers require the barbarian to take an action first. Unless otherwise noted, a barbarian cannot select an individual power more than once.
Totem rage powers grant powers related to a theme. A barbarian cannot select from more than one group of totem rage powers; for example, a barbarian who selects a beast totem rage power cannot later choose to gain any of the dragon totem rage powers (any rage power with “dragon totem” in its title).
