That sounds extremely busted. A global mass damage mitigation that doesn't cost your units any momentum to activate and also a global enemy nerf? On a status you can boost with Pray and extend void? That's even better than Adon Graxis, on a class that's already top tier. Maybe if it took four turns to invocate or something. But it also just completely loses the identity of the current iteration of the skill, with nothing in the game to replace it too. If you wanted it to be a global technique, then it should be more similar to Aquamancer's raincalling invocation, where you have to repeat it multiple times to get such busted effects.
