Blacksmith Ed
From Wikidsouls
Ride the lift down to Blacksmith Ed and you will soon discover that Ed is the grumpy and more talented brother of Blacksmith Boldwin. Although Blacksmith Ed does not sell any items, he can repair all weapons and shields and upgrade weapons with any Ores. Once Ed has the Flamelurker's Soul, he will be able to convert certain Demon's Souls into Unique Weapons. He is also able to upgrade some special weapons and shields with Colorless Demon's Souls.
Notes on Blacksmith Ed's Upgrades
In order for Blacksmith Ed to upgrade weapons with any Demon's Soul, you will need to give him the Red Hot Demon's Soul from the Flamelurker in Stonefang Tunnel, section 2-2. With the soul in your inventory, select the Talk menu option when you are talking to Ed, then keep selecting the talk option until he starts to repeat or offers to take the Demon's Soul from you. If he still does not offer to take the soul, walk away then approach him and start to talk again.
Note: Blacksmith Ed will only offer to take the Red Hot Demon's Soul if the Armor Spider and Flamelurker have been defeated on the current play through.
