The Blue Adobe Roof is a slanted royal blue block that you can use as a roof-tile or for other purposes.
It can be crafted in your Crafting Menu (default key "Q") after finding the raccording are crafting-Recipe for this block either in Iron Treasure Chests spawning on rocks of the Lava layer, or in Diamond Treasure Chests spawning on corrupted blocks like on the Corruption layer, or by obtaining it from Things or perhaps from Keepas of any kind; either as a loot or a pet-harvest.
To craft 8 Blue Adobe Roofs at a time you will need (as of R43 in May 2017):
- 2 Adobe Bricks, made by putting Mud in a Forge together with Fuel
- 1 Blue Pigment, made of Blue Flowers from Elderwood trees in a Processor or found in Obsidian Treasure Chests
- 3 Wood Slabs, made of any kind of Wood (except for corrupted wood) or Log in a Processor
- 1 Stone Rod, made of Stone, Limestone or Bedrock in a Processor
Since R42 in May 2017, inner and outer corners blocks can be created for Blue Adobe Roofs too by putting them into a Processor. No crafting recipes are required for this.
