Intelligence

Intelligence is an ability score and the primary ability of wizards.

Intelligence affects your Arcana, History, Investigation, Nature, and Religion skills. It also improves spellcasting for wizards, fighters (especially valuable for Eldritch Knights), and rogues (especially valuable for Arcane Tricksters), by increasing the chance of hitting an enemy with spell attack rolls, due to the increased Difficulty Class of spells with saving throws. In addition, it increases the maximum number of prepared spells for wizards.
