Displace

You warp time around a creature that you can see within range. The creature must make a Wisdom saving throw. On a success, the creature’s position in the initiative order is reduced by [roll]1d10[/roll] until the end of their next turn. On a failure, the creature’s position in the initiative order is permanently reduced by 10, and until the end of its next turn it can only move half its speed, and its AC is reduced by 2. A target can’t be affected by this spell more than once during the encounter. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature for each slot level above 2nd. The creatures must be within 30 feet of each other when you target them.
