Please offer some advice.

Hello. I play as Barbarians and would like to try my hand at PvP. In the Barbarian guide, I think there is a clear contradiction: on the one hand, it is recommended to level up the Life magic for a Barbarian, and on the other hand, it says that "Barbarians never get magic skills" (I personally level up Tactics more often, and sometimes Nobility). Or am I misunderstanding something?
