Demons of Denak

By briefly manifesting the Abyss within yourself, you create a sphere that brings forth a small hoard of invisible and vicious demons to tear space and matter. The sphere is centered on you and moves when you do, has a 20-foot radius, and lasts for the duration or until you are incapacitated or die. Whenever a creature of your choice starts its turn in the sphere, it must succeed on a Wisdom saving throw or you can instill one of the following effects against it:

• A warrior demon shreds the target’s physique, dealing 4d8 slashing damage on a failure and the target takes 1d8 for each attack it makes until the start of its next turn.
• A bloodlust demon whispers into the target’s mind. The target has disadvantage on its next attack roll. If it misses, it takes 3d6 psychic damage.
• A deceit demon speaks continuously to the target. Attack rolls against it are rolled with advantage and further deal 4d4 thunder damage.

If a creature targeted by this spell has any sense that allows it to see invisible or concealed creatures, it has advantage on the saving throw.
