Once you've achieved enough XP you will level up. Your Character Level increases by one and you get the following:
Skill Points: You get 5 points to spend at character creation, and skills can be a max of 5. You get a specific amount of skill points to spend at each character level and have a maximum you can get those skills to depending on character level. These are shown in the tables below. You can also gain skill points by doing something really good with that skill, training, or using a scholar's book.
