Alluring Defense (5e Feat)
From D&D Wiki
Prerequisites: Charisma 13 or higher
Ever the charismatic one, you have learned to use your strong presence as a shield during combat. You gain the following benefits:
- Increase your Charisma score by 1, to a maximum of 20.
- When wearing no armor and wielding no shield your AC equals 10 + your Dexterity modifier + your Charisma modifier (maximum of 3).
- If you aren't incapacitated, you can use your reaction to add your Charisma modifier as a bonus to your AC against a single attack or to one saving throw. Once you use this ability, you can't do it again until you finish a long rest.
