Temporal Restoration

You touch a willing creature and reach forward in time to when they are healthier to siphon that vitality back to the present.

The target regains 6d8 hit points. After 8 hours, the target then takes necrotic damage equal to the amount of hit points it was healed, which cannot be reduced in any way.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, both the healing and the damage taken increases by 2d8 per level of spell slot above 4th.
