Controlled Curse of Ra

Your hands embellow the spirit of the pharoah. You hold your arms out and fire a purple ray imbedded with the Curse of Ra. Make a ranged spell attack against the target. On a hit, the target takes 3d8 poison damage and must make a Constitution saving throw. On a failed save, it is infected with the Curse of Ra and must take 1d6 at the start of each turn.

Curse of Ra - On a failed Wisdom saving throw, the target can no longer speak, with any attempt being masked by a seemingly endless stream of sand pouring out from the mouth and shooting out of the nose. 1d6 at the start of every turn.
