Titan's Toxic Intent

Make a ranged attack with a Bow or Crossbow, a sickly green bolt streaks toward a target within range. On a hit, the target suffers the weapon attack’s normal effects as poison damage, and you can cause the target to take poison damage equal to your spellcasting ability modifier at the end of its next turn.

This spell’s damage increases when you reach certain levels. At 5th level, the ranged attack deals an extra 1d8 poison damage to the target on a hit, and the poison damage at the end of the targets next turn increases to 1d8 + your spellcasting ability modifier. Both damage rolls increase by 1d8 at 11th level (2d8 and 2d8) and 17th level (3d8 and 3d8).
