A way of changing catalysts on mirrored items

I would be against it.

an amulet with an annoint can be considered trash because certain annoints are just mandatory to make builds function, so GGG allowed a new oil to annoint mirrored ones.

an amulet with no/"wrong" catalyst is just slightly weaker... but still very much usable


reflective mist gambling is a gamble for a reason, could make an argument that jewelry from reflective mists should come with a random catalyst matching at least one of its affix's.
