HOW TO CRAFT DARK CRYSTAL AND HOW TO PUT OPTION IN ANY PARTS OF ARMOR PLZZ HELP
you will need:
1. crystal ( from Raphu)
2. Tears of Gods (from the Samurai Boss in warfare, the one in the horse, not the tank)
after acquiring these needed items, go to Miner Yumi in Biryu Commercial, she will craft your Dark Crystal.
PS: crafting is not 100% successful. i just crafted 2 sets yesterday and both failed.
