Vile Spore Bomb

You conjure a mass of toxic spores and launch it at a point you choose within range. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. A creature takes **8d6 necrotic damage** on a failed save or half as much on a successful one.

The area becomes difficult terrain for the next minute as thick spores settle across the ground, impeding movement.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
