Warrior's Tether

You target one allied creature you can see within range and create a copy of them that exists outside of this timeline.

When you cast this spell as an action, track that creature's current HP, active conditions, and all resources (including spell slots).

At the start of your next turn, the creature returns to the state that you tracked and returns to that HP regardless of healing or damage.

At Higher Levels: When you cast this spell with a spell slot of 3rd or higher you may target one additional creature for each spell slot above 2nd.
