Corrupted Leaves can be found on the Corruption layer attached to strands of Corrupted Wood in the shape of small treetops, some of these growing on the floor or from ponds of Corrupted Water, some hanging from the ceiling. Many of these treetops are rather hard to reach because of this. Theses Leaves make excellent Fuel for the Forge with a good heating factor providing quick progress, even though 4 of them have to be used up at a time for each process of smelting, baking, melting or hardening.
