Casting Aabraxi's Pestilent Swarm summons a 20 ft. Sphere of bugs. Any creature inside this swarm must make a constitution saving throw or take 3d8 poison damage and 2d8 slashing damage per turn. A creature that has made this save takes half damage. The creature can re-roll the save every turn. The damage triggers on the casters turn and when a creature starts it's turn in the swarm or enters it for the first time on their turn. Additionly, a creature who fails the save will have their movement speed halved.
