Once your character has gained enough experience points he or she will advance to the next level. Consult the table below to find out where these thresholds are. The following is a guide to leveling up your character.
Every 4th character level, you may increase one of your ability scores by 1. Increasing ability scores may increase your ability bonus as well. If so, then every skill and ability that depends on that ability will increase as well.
You get a new hit points each level for whichever class gains a level. Your Hit Points increase by rolling the Hit Die for your class and adding your Constitution bonus. If you have the Toughness feat, you may add extra hit points as well.

If your character has magic abilities, these will grow as your character progresses. While magic comes in many varieties, they all share a few common features. First, spellcasters have a pool of spells available to them. This pool may be a spellbook, a familiar’s knowledge, intuitive understanding, or a set list of divine spells available. The pool of available spells grows as the spellcaster progresses, adding more spells and spells of higher levels. Second, spellcasters must select certain spells to prepare each day. The process of preparation is different depending on the spellcaster, but usually the number of spells prepared each day also grows as the spellcaster levels up. Third, spellcasters must expend slots to cast spells. These also increase over time. Slots are expended upon casting and are usually regained daily, with some exceptions. The combination of different way to cast, prepare, and get access to magic make each spellcaster a bit unique.
Classes gain new abilities and techniques at some levels. Check your class description for a list of new abilities that you now know. Old class abilities may also level up, so you may want to review all of your old class abilities as well.
