Endpoint Refiner is a rare-tier upgrader that has a minimum upgrade value of 60% (1.6x multiplier), it increases if the ore was previously upgraded. The more the ore is upgraded, the larger the multiplier from this item. It can only be used with a Large Conveyor Ramp or Raised-ier Conveyors from the side.
