In Dark Souls 3 you can get Coals that will upgrade your Blacksmith’s abilities. These Coals are scattered through the lands and can easily be missed if you don’t know where the look. Check out this Dark Souls III Blacksmith Coal Location Guide to find them all!
Dark Souls 3 Blacksmith Coal Location GuideWhen you get the Coal, bring it to the Blacksmith to upgrade him.
From the island you are on now you should see a wall to the left, another small island with a fire to the right and one of the Towers you need to put out, and in front of you should be a bunch of nasty looking trees with sacks hanging off of them and the poison swamp. We are going through there. On the other side of the swamp you will see a Tower and inside you can find the Coal. There is an Undead Knight protecting it so be ready.
If you follow the path you can get behind the knight so you don’t have to fight him. At the end of the path behind the Knight you will find the Coal. The knight is really strong, killed me in two shots, so if you fight him be ready.
I am updating this as I go so check back soon for updates!
