Ethereal Tether

You create a magical tether between a creature's soul and its body. Touch a creature that has died within the last 10 minutes. For the duration, the soul remains anchored to the body, preventing it from departing to its afterlife. This spell makes resurrection spells easier to complete by lowering an DC checks you might have implemented in your game. It also removes the material cost of the 300gp diamond on Revivify so long as it is cast during the duration of this spell.
