Beetle Swarm

5th-level conjuration

Casting Time: 1 action

Range: 120 feet

Components: V, S, M (an embalmed beetle husk)

Duration: 1 minute

You summon a swarm of fiendish beetles from the Abyss, which coalesces out of swirling dark smoke at a point you can see within range. Though the beetles are flightless, they can adhere to walls and ceilings, and they begin to devour organic material in their area.

Creatures that enter the area for the first time or begin their turn in the area must make a Constitution saving throw. Those that fail suffer 5d6 slashing damage and are blinded as beetles swarm over them. A creature that succeeds takes half damage and is not blinded. If a creature leaves the area of the swarm, they continue to take 3d6 slashing damage at the start of each of their turns for the duration as tenacious beetles cling to them. A creature may use its action to brush the beetles from the target. Those beetles immediately scurry back to the main mass.

At Higher Levels. When you cast this spell using a spell slot of 6th or higher, the damage while inside the swarm increases by 1d6 for each slot level above 5th.
