Sleep of the Deep

3rd-level illusion (ritual, mythos)

Casting Time: 1 action
Range: 60 feet
Components: V, S, M (a pinch of black sand, a tallow candle, and a drop of cephalopod ink)
Duration: 8 hours

Your magic haunts the dreams of others. Choose a sleeping creature that you are aware of within range. Creatures that don’t sleep, such as elves, can’t be targeted. The creature must succeed on a Wisdom saving throw or it garners no benefit from the rest, and when it awakens, it gains one level of exhaustion and is afflicted with short‑term madness.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can affect one additional creature for each slot level above 3rd.
