Fargo's Mod/Amalgamated Spirit

The Amalgamated Spirit is a item used to simultaneously summon a Necromancer, Diabolist and Ragged Caster. It can be bought from after one of them has already been defeated, Plantera has been defeated and the world is in Hardmode.

The Amalgamated Spirit 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 skeleton mages will not spawn and the item will not be consumed.
