Therefore, I'd say that Master Refiner is pretty useless.
I noticed catalysts definitely don't have the same effect as in past versions of Seal Online. For example, in my case, even FIVE lvl 18x armors aren't enough to give me 100% success on a G13 refine. Nowadays, you pretty much have to use the item mall armors to get 100% success for high level refines. So, find some cheap lvl 160+ XG equips with bad opts and use them as catalyst. Maybe throw in a couple 18x armors if Pink Diamond isn't enough.
Hope this helps.
