Modifies the outcome of a craft when upgrading an affix.
Randomly changes the upgraded affix to a different one that can spawn on that item type. It cannot change a prefix into a suffix or vice versa.
For example if you use a fire resistance shard to a raise the tier of a fire resistance suffix the tier would increase as normal and then it would change into a different affix such as cold resistance or increased health.
