What cretiiqe Would you offer?

This is 4th edition right?
Just heal the damage directly (temporarily).
Probably easier.

It was meant to be the ars magica version of the merciful weapon effect.

It seems what you're trying to do is in 2 parts;

  1. prevent damage incoming, whether by MuCo or ReTe
  2. do fatigue damage instead, which would be PeCo.

This is, in fact, more difficult than just stopping the damage.
