Cantrip Primordial, Conjuration
You produce a cloud of virulent spores. Each creature within 5 feet of you, other than you, must succeed on a Constitution saving throw or take 1d4 poison damage. A creature that fails the saving throw by 5 or more is poisoned until the end of its next turn.
The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
