Telekinetic Strangulation

You make a spell attack roll, contested by a Strength check from the target, the target has advantage if its size is huge or larger, and the target automatically succeds if it does not need to breath, such as a construct or undead creature.  If the target wins, the spell ends, causing it takes force damage equal to the casters spellcasting ability modifier + the spells level, and the target suffers no other effect.  If you win the target is telekinetically lifted 5ft into the air, and restrained.  The target can make additional contested checks, as an action, on their turn, a number of times equal to the targets Constitution modifier, (minimum one), if any of these additional checks are successful, the spell ends, the target takes the same damage as if they had succeeded on the first check.  If the target is held for a number of turns equal to their Constitution modifer, they are dropped to 0 hit points, rendered unconscious, but stable.  The spell can be held for another round after that, and the creature is automatically killed.

At Higher Levels. When you cast this spell using a slot of 3rd level or higher, you can target an additional creature for every 2 levels of spell slot, (2 at 4th, 3 at 6th, 4 at 8th).
