Chaos Warp

You wave your hands around your body, creating a smoky shroud that becomes charged with arcane energy. At the start of your turn, a random creature within 30ft of you that you see makes a Wisdom save. On a failure, the creature takes 2d6 force damage and is forced to switch its physical location with your own, but on their success, you take 1d6 force damage as the spell backfires and you don't switch. The randomly selected creature must fit in the space you occupy, or the spell backfires automatically, dealing 1d6 force damage to yourself and causing no location swap.

At Higher Levels. The damage increases by 1d6 (to both you and the damaged creature) for each slot above 3rd.
