Bacterial Barrage

You attack a creature in range with a quick spreading infection that takes advantage of existing conditions. Make a ranged spell attack against a target, on a hit the infection does 1d8 necrotic damage to the target. If the target is suffering from the Poisoned] condition or a disease, it instead takes 1d12 necrotic damage.

The spell's damage increases by one die when you reach 5th level (2d8 or 2d12), 11th level (3d8 or 3d12), and 17th level (4d8 or 4d12).
