So I heard from a friend that if you heat your item to higher levels, then alchemize it, that you will have a chance at getting better UV's. This applies to mostly 2 and 3 star stuff cause you have to heat 4 star stuff to level 10 to alchemize anyways. For example, if you heat your chroma mask to level 10 it will have a higher chance of getting a good UV or a UV at all rather than a chroma mask at level 5 which will get a low UV or no UV at all. Can anyone confirm if this is true?
I have never heard this rumor or seen any data about this. Your friend almost certainly does not have the detailed data needed to support such an assertion. Almost certainly it is false.
