Intelligence

Memory and mental power.

Intelligence is an Ability Score and the primary ability of Wizards.

Intelligence affects your Arcana, History, Investigation, Nature, and Religion skills and improves spellcasting for Wizards, Eldritch Knights and Arcane Tricksters (better chance to hit enemies with Spell Attack Rolls; increases the Difficulty Class of spells with Saving Throws).
