From publisher blurb:
100% Concentrated RAGE!
Legendary Barbarians is the latest volume in our series of class-focused player supplements, this time focusing on the fearsome barbarians! This core class has long been a staple of fantasy settings, representing both the power of anger and the rejection of civilization. Legendary Barbarians enhances these ideas with a streamlined redesign of the class that provides flexibility, power, and flavor, able to customize the benefits of your rage to open up an incredible variety of savage soldiers! Enlarging rage increases the barbarian’s size (Hulk Smash), while invincible rage lets her shrug off attacks with ease. Bestial rage transforms the barbarian to an animal and vicious rage sacrifices her hit points for greater damage.
Dozens of rage powers and alternate class features allow a piece-by-piece construction of your perfect barbarian, while 11 new archetypes (such as the mutagenic rager, slavering nightmare, and righteous berserker) tie your abilities together in a theme, like the savage that trades rage for a more stoic approach and the fury that just can't stop raging! All this, plus tons of new feats like Wield Halfling, magic items like the totemic club, barbarian brands, unchained support, sample character builds, and more, including a ready-to-use legendary barbarian, Gorund Wildwalker!
