Yhwach's future seeing immunity might have a weakness though, while any power he can see he becomes immune to getting cut or blugened is not a thing you can adapt to unless you are just air or water.

Case in point Dc Comics' Doomsday creature, any energy or being that can harm or kill it is adapted to and overcome, but physical trauma is still a weakness because you can only become more durable to that instead of immune to energy and diseases and stuff.

If Nimaiya had cut Yhwach with his eyes "open" he wouldn't be immune to it, at least that is what I think considering that Yhwach has seen a Getsuga Tensho before and it still managed to hurt him,
