Medium spiky mithril salvage is a salvage item introduced with the Mining and Smithing rework. Salvage has no use other than disassembly, alchemy, or trading.
Medium spiky mithril salvage is worth 1,800 coins in high level alchemy. When dropped by a monster, it can automatically be alchemised by a spring cleaner 2000 or higher at the cost of a spring (1,174 coins profit); alternatively it can be automatically disassembled for free by a spring cleaner 3000 or higher. Because it does not use a spring, automatic disassembly does not advance the spring cleaner towards its next upgrade. Dismantle mode does not work on salvage items.
When the rework was launched, the following items on monster drop tables were replaced with medium spiky mithril salvage:
Medium spiky mithril salvage can also be bought from Elof for 30 mithril item tokens.
