Radiant Emotions (5e Feat)
From D&D Wiki
Prerequisites: You must be a Diamond of the Gem race.
You have learned how your aura can manipulate the feelings of Gems around you. Using your action, you may create a 60ft sphere of pure emotion centered on your gemstone. Each Gem beginning its turn within this sphere must make a Wisdom saving throw or be frightened for the turn. This field lasts up to 1 minute or until you lose concentration. The save DC for this is 14 + your Wisdom modifier. You may use this a number of times equal to your Wisdom modifier +1 (min 1) and you regain all uses of this trait during a long rest.
