"A strong upgrader which accepts raised conveyors from the sides. Prefers already well-upgraded ore."
The Endpoint Refiner is a rare-tier upgrader that has a minimum upgrade value of 60% (1.6x multiplier), which 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, Raised-ier Conveyors, or an Ore Hoister from the side. The ore has to be upgraded at least 20 times in order for them to work with the Endpoint Refiner.
