A refinery is a structure consisting of a dropper and an oak fence post. This structure is required to process your mysterious dust into other usable items, as well as for crafting vessels.

How To Build: Place a dropper facing upward, and the oak fence on top of it. It is okay for the fence to attach itself sideways to an adjoining wall. Once built, place the mysterious dust inside the refinery to process it into its different components. Alternatively, place all 8 pieces of a Vessel in there to craft a Vessel.

Mysterious Dust

Mysterious dust drops from mining ores, and can also be obtained from identified artifacts. When refined, mysterious dust may return nothing, one item, or more than one item. Refer to the refinery to properly use mysterious dust.

  • At all PyroMining levels, it has a 75% chance of returning Rune Dust.

  • At level 20 or higher, there is a 2% chance to obtain Oracleite (uncharged, later used to summon the first Oracle miniboss).

  • At level 25 or higher, there is a 4% chance to receive Ancient Relic.

  • At level 30 and greater, Shattered Requium Orbs may drop.
