Equipment siphons are used to drain item experience in order to obtain Invention experience without destroying the item. This method requires buying enchanted gems and making them into rings of slaying, followed by disassembling them along with magic shortbows and maple logs to acquire the components necessary for creating the equipment siphons. It is recommended to purchase enchanted gems from Turael or Spria in Taverley and Mazchna in Canifis. This will allow for 600 gems to be bought every 24 hours. The rings can then be crafted using Edgeville's furnace or by using a portable forge.
