You send forth a spear of condensed magical power towards a creature you can see within range. The creature must make a Dexterity saving throw. On a failure, it takes 12d8 Force damage and they cannot use any conjuration magic or any similar effect that would allow them to teleport between locations or between planes of existence like the plane shift spell, so long as you are concentrating on the spell.
At higher levels: When you cast this spell using a spell slot of 8th level or higher, the damage increases by 1d8 and you can target an additional creature for each slot level above 7th.
