When you cast Blighted Bulb, you bury a plant bulb attached to a small bone into to ground and transform it into an undead version of itself. The plant takes on a sickly, dark hue as necrotic energy infuses it. The blighted bulb lies dormant until a creature comes within 5 feet of it.

When a creature comes within 5 feet of the blighted bulb for the first time on a turn or starts its turn there, the bulb explodes in a burst of necrotic energy. The creature must make a Dexterity saving throw. It takes 3d8 necrotic damage on a failed save, or half as much damage on a successful one.

The blighted bulb can be targeted and destroyed (AC 10; hp 10; vulnerability to fire damage; immunity to poison and psychic damage).

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
