Upon arriving on Urk-Daonassar, you may chat with the Orc armor and weapons merchant, and he will tell you about the Legendary Blacksmith. You will need either INT 4 or PER 4 check to learn that this blacksmith, in fact, was last seen on the Dragon Mountain. You will go the Dragon Mountain area, and after fighting your way through the overwhelming numbers of cunning Goblins (Hobgoblins and Dragon Priest alike), Drakes, and powerful Dragons, you will find a cave where someone definitely lives there. You will find some racks of weapons and armors, piles of straws, ponds of clean and drinkable water, and some space that looks like kitchen. You will encounter an Orc, named Xnaurl Steelbringer. He will ask you to find him or buy him a golden bolt for his blacksmith tongs. The racks, the straw piles, the ponds, and kitchen will all be interactable. (is this even a word? lol) The fastest way is to approach the piles of straws and find the bolt among them, and if you have AWA 5, you can find the golden bolt among the straws. This option will earn you the Achievement "Eyes Sharper than even Diamond" or "Hawkeye". Alternatively, you can just buy the bolt in Urk-Daonassar armor/weapon trader. Returning the bolt to Xnaurl will earn you the "Goblin Slayer" short sword with Beast slayer attribute. The short sword will have the highest attack speed that could rival a dagger. Xnaurl will now be able to craft you a special weapon: choose any basic non-elemental weapons (Iron, Steel, Bluesteel, and Silver), and as for bow, only Short Bow, Hunting Bow, or Oak Bow, and then choose an element for it:
- 2 Rubies or 5 Fire Salts = Fire, alternatively: 1 Ruby and 3 Fire Salts
- 2 Sapphires or 5 Living Ices = Ice, alternatively: 1 Sapphire and 3 Living Ices
- 2 Pearls or 5 Sparkling Powders = Thunder, alternatively: 1 Pearl and 3 Sparkling Powders
- 2 Chitin Carapaces or 10 Small Diamonds = Spirit, alternatively: 1 Chitin Carapaces and 5 Small Diamonds
- 20 Zombie Fleshes or 10 Skulls or 2 Demonic Skulls = Death, alternatively: 10 Zombie Fleshes and 5 Skulls, or 5 Skulls and 1 Demonic Skull
- 4 Giant Mamba Fangs or 2 Coral Snake Fangs = Toxic/Poison, alternatively: 2 Giant Mamba Fangs or 1 Coral Snake Fangs
and, dojyaaan! You have yourself a weapon with +5 customized elements, and more powerful than the available one.
I want to add Attribute, but I'm still confused as to how, and the weapon would be way too OP.
