Components: V, S
Duration: Instantaneous
A 20-foot radius Sphere of gloom erupts from a point you choose within range as fell energies from the dimension of shadow flood the area. You select an entity to push through into this reality for a horrifying moment. When you cast this spell, choose one of the following options:
The Darkness Hides Terrors. Creatures of your choice in the area must make Dexterity saving throws. A target takes 4d8 psychic damage on a failed save and must use a reaction to move as far away as it can from the point you chose, using the safest route. On a successful save, the target takes half as much damage only.
Tomb of Shadows. Creatures of your choice in the area must make Constitution saving throws. A target takes 4d8 necrotic damage on a failed save and its speed is reduced by 20 feet. On a successful save, the target takes half as much damage only.
Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 3.
