Prerequisite: Charisma score of 15 or higher
You can cast Suggestion once per long rest without expending a spell slot or requiring material components.
When you cast Suggestion this way, you can bypass the usual restriction that the suggestion cannot directly cause harm to the target. The suggestion must still be phrased in a reasonable manner the target could interpret as beneficial or compelling (GM discretion). The target also has disadvantage on the saving throw when cast this way.
Charisma is your spellcasting ability for this boon, and the save DC is 8 + proficiency bonus + Charisma modifier.
You are also immune to charm
