Banishment
You employ sheer force of will to make reality question the existence of a nearby creature, causing them to warp visibly in front of you.
Until the spell ends, a target native to your current plane is banished to a harmless demiplane and incapacitated. At the end of the duration the target reappears in the space it left (or the nearest unoccupied space). A target native to a different plane is instead banished to its native plane.
At the end of each of its turns, a banished creature can repeat the saving throw with a –1 penalty for each round it has spent banished, returning on a success. If the spell ends before its maximum duration, the target reappears in the space it left (or the nearest unoccupied space) but otherwise a target native to a different plane doesn't return.
Duration: Concentration (1d4+2 rounds; the Narrator rolls in secret)
The duration of banishment increases by 1 round for each slot level above 4th.
Komanov’s Icy Displeasure. Until the spell ends, the target is vulnerable to cold damage and it has disadvantage on ability checks and attack rolls .
