Holy mould

A holy mould allows a player to make Unstrung holy symbol through the Crafting skill, granting 50 experience. To make it, one needs to use a silver bar on a furnace, while having the mould in the bag. This requires level 16 crafting.

The Unstrung holy symbol can be transformed into a holy symbol by using a ball of wool on it, granting 4 experience.

You can buy a holy mould for 5 coins at Dommik's Crafting Store in  Al Kharid or take one from the respawn point in the second story of the Crafting Guild.
