Ring of forging

A Ring of Forging can be made by enchanting a ruby ring, using the spell Enchant Level 3 Jewellery. If a player smelts iron ore while wearing the ring, it gives a 100% success rate. However, after smelting 140 iron ores while wearing it, the ring disintegrates. The number of times before it disintegrates depends on the wearer, not the ring. For example, if you smelt 139 iron ores, and sell the ring you were wearing, the buyer would have 140 uses unless s/he has had a remaining number from before.
