Undead Swarm

Using an action, you may call upon the dead to serve you in battle. You may animate up to three corpses that you can see within 30 feet of you. The corpse turn to ash upon the spell ending.

Each corpse has 45 hp. If a corpse is reduced to 0 hp before the spell ends, it swells up and explodes in a cloud of spores. Each creature within 10 ft of this explosion must make a constitution saving throw equal to your spell save dc. If they fail they take 3 d4 poison damage.

Each corpse acts on your initiative and deals 1 d6 necrotic damage upon a successful strike.

You may animate one additional corpse for each spell slot above 6th level.
