The Iron Roof is a slanted building-block with a topside looking like rusty iron.
This slanted block can be placed to create corners of walls or for other purposes too when being rotated by pressing and holding R (as the default key) while moving the mouse.
Iron Roofs can be crafted in your Crafting Menu (default key "q"), but only after the crafting-recipe has been unlocked by:
To craft 8 (blocks of) Iron Roofs, you'll need:
- 1 Glob of Goo crafted from Mold in the Crafting Menu or looted/harvested from creatures
- 1 Obsidian Rod made of Obsidian bars in a Processor
- 2 Iron Rods made of Iron Bars in a Processor
- 4 Iron Slabs made of Iron Bars in a Processor
Crafting or taking Iron Roofs is one of the unlocking requirements of the crafting-recipe for Diamond Roofs.
