Fargo's Mod/Attractive Ore

Attractive Ore is a item used to summon an Undead Miner. It can be bought from after one has already been defeated.

Attractive Ore will only work at night or if the player is underground (at or below the cavern layer). If used during the daytime or above the cavern layer, the Undead Miner will not spawn and the item will not be consumed.
