Venom Bolt

A glob of sickly green poison hurtles towards a creature within range, vaporizing into a small cloud of toxic mist. The target must make a Constitution saving throw or take 1d4 poison damage. The target must make an additional Constitution saving throw at the beginning of each of their turns, taking 1d4 poison damage on a failure. If the creature succeeds on the throw, the effect ends.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
