Telefrag

Choose a creature you can see within range. You teleport directly into that creature's space and explosively displace its body. The creature must make a Constitution saving throw, with advantage if it is 2 or more sizes larger than you, taking 10d10 force damage on a failed save or half as much on a successful save.

If this damage reduces the creature to 0 hit points, its body violently explodes and you appear in its space. Otherwise, you are shunted to the nearest unoccupied space and take 5d10 force damage.

At higher levels: For each spell level above the 5th, add an additional 2d10 force damage to the target and 1d10 to you for a maximum of 18d10 to the target and 9d10 to you.
