Choke

The caster may target a creature within this spells range, that creature must succeed a Constitution saving throw with disadvantage at the start of each of it's turns for the spells duration. If they fail: they take 1d6 Choking damage, each time they fail a save, the damage increases to 1d8, 1d10, and finally 1d12 at maximum. If the target succeeds a save, the damage is reset. The spell ends if you lose concentration, or the target dies/falls unconscious. This spell has no effect on creatures that lack lungs.

At higher Levels: The damage the creature is dealt increases equal to 1/2 the level of the slot you used for this spell that is higher then 2nd.
