Help Index :: Attributes :: Intelligence Intelligence is one of the five basic character stats (Strength, Intelligence, Wisdom, Dexterity, and Constitution). Intelligence determines how many spells you may cast before needing to rest, as well as how fast your spell energy regenerates. Along with wisdom, intelligence also affects the rate at which you can absorb and improve new skills. Intelligence is an important stat for spellcasters, such as mages and clerics. It is also important to rangers and paladins who wish to be able to wield a large repository of spells.
