Can a Barbarian use spring attack while raging. I ask this because in the core rulebook on p 32 under the rage section it states that "while in rage, a barbarian cannot use any Charisma-, Dexterity-, or Intelligence-based skills(except Acrobatics, Fly, Intimidate, and Ride) or any ability that requires patience or concentration.
Spring attack is not a skill. Moreover, IMO, it not takes so much patience to run, bash someone else's nose, and run away.
So, I see definitively a barbarian able to spring attack while raging.
Barbarians are even known for thie quickness. Hence 40ft move rate.
I agree with Kaiyanwang.
