A dragonbane bar is made by smelting dragonbane ore, requiring level 77 Smithing and giving 50 experience. It can be made into dragonbane arrowheads at level 80 Smithing and dragonbane bolts (unf) at level 82 Smithing. Any part of the creation process can be assisted.
The bar is only usable on one of the anvils at Kethsi. One of these anvils may be accessed via the fairy ring system using the code dir, followed by aks. The other may be accessed via the World Gate.
If a player tries to use a dragonbane bar on a normal anvil, they will receive the message: You don't seem to be able to forge this bar on an ordinary anvil.
It can be used to fill a strong smelting urn.
