Acidic Kiss

You drain your lips in acid and kiss a creature who is in melee range. A target must succeed on a Dexterity saving throw or take 1d6 acid or poison damage and it poisons the opponent.
On a failed save the target takes half the damage.

At Higher Levels. When you cast this spell using a higher spell slot, the damage increases by 1d6 for each slot level above 1st
