The Fire Jet is a block added by the Twilight Forest mod. Fire Jets can be found in the Twilight Forest's Fire Swamp.
Uses[]
Fire Jets are only used in the crafting of the Encased Fire Jet.
For any Fire Jet to activate, there must be a 3x3 hole underneath the jet filled with lava.
The only non-aesthetic function of a Fire Jet is startling others that may be near the Fire Jet.
