Horus's Blessing

Horus grants you the power to defend yourself and your allies with radiant light. You can use your action to create a blast of radiant light and make all enemy creatures within 15ft of you make a CON saving throw (DC equal to 8+ CHA mod+ proficiency bonus) or take 5d6 radiant damage on a failure and half as much on a success. Regardless of the results of the saves, all allies within the same radius regain health equal to half of the damage rolled.
