Another multi-class question.
Let's say a 1st level Barbarian, when he gains enough XP to go up a level, selects Borderer as his new multi-class. Now, he's a 2nd level character: Barbarian 1/Borderer 1.
When he gains enough XP to make it to a 3rd level character, how does he chose which class is increased to the next level? Is this just player's choice?
So, a Barbarian 1/Borderer 1, who gains a level, can become a Barbarian 2/Borderer 1, or he can become a Barbarian 1/Borderer 2.
Is that correct?
