You can take the Influence action to attempt to befriend a creature you can see within 30 feet of yourself that can hear or see you. The creature must succeed on a Wisdom saving throw (DC 8 plus Charisma modifier and your Proficiency Bonus) or have the Charmed condition for 1 minute or until it takes damage. While it has the Charmed condition, it is friendly to you and your allies.
Once you use this feature, you can't use it again until you finish a Short or Long Rest unless you expend one Battle Die (no action required) to restore your use of it.
