Beguiling Words

You have honed your psychic magic to influence the minds of your opponents, granting you the following benefits:

• Your Charisma score increases by 1, to a maximum of 21.
• You can cast the command spell once per day if you cannot already.
• On your turn, as an action, you can speak magically enchanted words into the ears and mind of a creature within 60 feet of you that can hear you. That creature must make a Wisdom or Intelligence (target's choice) saving throw against a DC of 9 + your Wisdom modifier + your proficiency bonus, taking 1d6 psychic damage and be charmed by you for 1 minute on a failure, or take 2d8 psychic damage + 1d4 poison damage but no other effects on a success. While a creature is charmed by you, at the start of each of its turns, it can repeat the saving throw and end the charm effect on itself on a success.  After using this ability, at the start of your next turn, roll a d6. On a 4 or higher, you can use your Beguiling Words again. 

If you choose this feat again at a higher level (or higher growth stage), the ability has no recharge.
