I refine based on the calculator and it's been spot on the whole time (when it says 100% I get 100%). Although I'm not as experienced as most others are.
Yes they have different rates. The rate for clothes is slightly lower. the reasoning behind this I imagine has to do with the fact that dragon blood can easily be farmed or bought from item mall to prevent clothes from breaking from a failed refine so you basically have infinite chances to refine to max level. weapons in the other hand once you run out of tries you need a mirror to reset hardness which are harder to come by. Hence the ever so slightly better refine rates for weapons. makes barely any difference though but there is a difference between the two
can be farmed since a year bro. Can drop from Loulan Ancient chest. Same tears and scales. Everyone who farms there in regular bases should have several stacks of tears/scales/Dragon Blood by now.
