Barbarian enhancements (history)

Note that enhancements do not stack with other enhancements from the same series. Each element of a series requires everything previous in that series before it can be taken.

Action Boost Enhancements
Boosts last 20 seconds and can be used 5 times per rest. They have a 30 second cooldown. (Shared by all action boosts.)

Prestige Enhancements
A character can train in only one Barbarian Prestige path at a time. Each has both passive benefits and active benefits, which expends hit points to get the specialty. All requirements must be taken from Barbarian class enhancements.

Capstone
A character can train only in one Barbarian Capstone at a time.
