I just started playing the game and beat up a bunch of orcs. I leveled to level 2, which gave me 5 attribute points and 2 skill points. Now, I see in the character menu, "Unspent Skill Points: 2" and "Unspent Attribute Points: 5", but there is no obvious way to spend these. I don't see any keyboard keys in square brackets on this menu. How do I spend these points?
