Red Adobe Stairs are pinkish-red building-blocks cut into an L-shape.
Usually placed as stairs they will smooth the player-character's movement up and down gradients so no jumping is needed. They can be placed as projections of walls or for other purposes too when being rotated by pressing and holding R (as the default key) while moving the mouse.
Red Adobe Stairs can be crafted in your Crafting Menu (default key "Q"), but only after the crafting recipe has been unlocked.
To unlock the crafting recipe for Red Adobe Stairs, you will have to craft Red Adobe Walls and process Red Adobe Slabs from blocks of Red Adobe Walls by simply putting them into a Processor. No crafting recipe has to be unlocked for that.
The crafting recipe for Red Adobe Wall is unlocked by finding the rare Recipe for it in a Treasure Chest or maybe obtain it from a Thing that spawns on corrupted blocks.
8 Red Adobe Walls each can then be crafted with 2 (blocks of) Adobe Bricks, 4 blocks of any kind of Canyonstone (like Ruddy Canyonstone, Dark Canyonstone or Canyonstone), plus 2 Stone Rods made of Stone, Limestone or Bedrock in a Processor, 1x Melted Wax made of Beeswax in a Forge or found in Treasure Chests and 1 Red Pigment made from Red Flowers (from Ashenwood trees or Wood Treasure Chests) in a Processor. To craft 4 (blocks of) Red Adobe Stairs at once, you'll need
- 2 Red Adobe Slabs made of Red Adobe Wall in a Processor
- 1 Stone Rod made of Stone, Limestone or Bedrock in a Processor
- 2x Melted Wax made of Beeswax in a Forge or looted from Wood Treasure Chests or Stone Treasure Chests
Since R42 in May 2017, inner and outer corners blocks can be created for these stairs too by putting them into a Processor. No crafting recipes are required for this.
