how difficult is to refine to +16, +17 and +18? is the difficulty depends on Weapon level requirement as well? any tips/tricks on refining? apparently, i already used 20x Mirror of Ancient Dragon just to refine from +17 to +18? i did some kinda' tricks that my friends did but unfortunately i have no luck at all or probably couldn't find the trick on that "RNG". so sad i doesn't have a luck on this game.
fORTUNE IS THE TRICK... Refine until you hit a streak.. you can try refining and breaking weapons then refime..
yeah that is what i actually did, breaking some weap. then refine and repeat but the "RNG" sucks everytime never had that fortune i even crossed my toes and my knees lol
