Vel'kyn's Stasis

You create a temporal shield around a creature other than you within range that you can see. temporarily delaying harm. For the duration, each time the creature would take damage, the damage is instead pushed into the future. When the spell ends, the target takes all of the damage at once.

This damage cannot be reduced by anything other than the resistances and immunities it has at the time that the damage was delayed. The spell ends early if the target moves outside the spell's range or if you lose line of sight.
