Force of personality.
Charisma affects its related skills (Deception, Intimidation, Performance, Persuasion) and improves spellcasting for Bards, Paladins, Warlocks and Sorcerers (better chance to hit enemies with spell attack rolls; increases the Difficulty Class of spells with saving throws).
As of Early Access Patch 9, increasing one's Charisma Modifier also improves the prices offered by Traders (by increasing the Persuasion skill bonus).
