Asphyxiation

You squeeze the air out of one medium humanoid, fey, fiend, celestial, beast, aberration or monstrosity that you can see. The target must make a constitution saving throw. on a failed save, you use an invisible force to crush the throat of a target. The target is then subjected to choking. A creature being choked must take 2d12 damage per turn due to air loss. a choked creature can repeat the saving throw at the start of its turn, falling prone and ending the spell on a success. A creature that doesn't need to breathe is not affected by this spell. If the creature casting this spell has the tandem casting feat, this spell can be used in tandem with the grapple spell (homebrew), requiring 2 spell slots to tandem cast. A creature tandem casting with this spell can use 2 actions on their turn, but both actions must be used to maintain the tandem spells.
