The Eladrins innate spellcasting ability is Charisma (DC16)
Sorrowful Presence. Any non-eladrin creature that starts its turn within 60 feet of the eladrin must make a DC 16 Wisdom saving throw.

The creature can repeat the saving throw at the end of each of their turns ending the effect and becoming immune to Sorrowful Presence for the next 24 hours. Whenever the eladrin deals damage to the charmed creature, it can repeat the saving throw. Fey Step (Recharge 4-6). As a bonus action, the eladrin can teleport up to 30 feet to an unoccupied space it can see. Magic Resistance. The eladrin has advantage on saving throws against spells and other magical effects.
