Sometimes, all you need to have fun with a class for another few months is a few new ideas to tinker around with. Class Expansions is a series of lightweight supplements for The Pathfinder Roleplaying Game that takes a base class and offers alternative class features that, handily enough, each fit on one page or less.
Following in this vein, Class Expansions: Barbarian Rage Powers introduces, funny how this works, twenty-one new rage powers.
Think of these descriptions as fortune cookies, but use "...while raging" instead of "...in bed".
Aligned Fury - Your attacks carry your alignment.
Bone-Hewing Strike - As a standard action, hew bone and stagger a foe.
Burning Hatred - If dealt enough damage by a single blow, your next round of raging is free... if you attack whoever hit you that hard.
Burning Hatred, Greater - If dealt enough damage by a single enemy, your next round of raging is free... if you attack whoever hit you that hard.
Crushing Blows - You treat your base attack bonus as 2 higher for the purpose of Power Attack.
Crushing Blows, Greater - As Crushing Blows, but 4 instead.
Extraplanar Embodiment - Gain a bonus to your DR, but the type changes from / - to one based on your alignment.
Fearful Display - Intimidate everyone in a radius around you.
Fury Made Placid - You gain a bonus to saving throws while using your moment of clarity rage power.
