How to get the huge furnace of the Phantom Beast Palu
The huge furnace is unlocked in the technology menu. The unlocking condition is to reach level 56 and requires 5 technology points. Once you unlock this structure in the Technology menu, you'll need the following materials to craft it:
150x plastic steel
100x Polymer
200x Fire Breathing Organ
20x Ancient Civilization Parts
The fire-breathing organ can be obtained by defeating the fire-type Palu, and the ancient civilization components are dropped by the boss Palu scattered throughout the map.
Polymers can be made in any production assembly line using high quality pallu oil. Alloy steel can be made in an electric furnace. Once you have collected all of these materials, place the Giant Forge within your base.
It should be noted that the Great Furnace requires electricity to operate, and requires a palu with the ability to ignite. Make sure you have at least one Electric-type Palu working on the Electric Generator in your base.
