Infusion Coals are key items in Dark Souls 3. When taken to Andre, the blacksmith, they’ll unlock different kinds of infusion.
These will let you change the type of damage your weapon does. There are four of them in the game, and each unlocks several types of infusion. In this guide, we’re going to show you all infusion coal locations in Dark Souls 3, which infusions they allow.
Infusion types: Heavy, Sharp, Poison
You can find this coal in the Road of Sacrifices. Spawn at the Halfway Fortress bonfire, then go down the road. When you reach the swamp, turn right and go all the way to the wall. Go through the door and turn left. Follow the corridor, past the Black Knight. The coal is on a pile of rubble at the end of the corridor.
Infusion types: Crystal, Blessed, Deep
This coal is in the Road of Sacrifice as well. Teleport to the Farron Keep bonfire, go into the swamp and head left, following the wall. You’ll see a tower at a certain point, guarded by a single Darkwraith. Defeat him and enter the tower. The coal will be on a corpse inside.
