Temporal Shell

You create a temporal shield around a creature other than you within range, keeping incoming wounds at bay by slowing them down. For the duration, each time a creature would take damage, the damage is instead shunted into the future. When the spell ends, the target takes all shunted damage at once.

No part of this damage can be reduced by anything other than resistances and immunities it had at the time that damage was shunted. The spell also ends early if the target is ever outside the spell's range or if it has total cover from you.
