"Sacrifice your ore to the underworld and receive back 7x the ores' value. Gives 5 points per 80 ore."


The Sacrificial Altar is a Unique-tier furnace bought in the Shop for $1.37T. Ore "sacrificed" to the furnace is, as the item's description states, processed at 7x ore value. It goes along with the underworld theme of the Painite Mine, Sacrificial Cell, and Cursed Ore Purifier.


  • The Heavenly Forge is better than this furnace with ores worth less than $250. (although this isn't a very useful tip)
