Dark Lumite Stairs are dark purple glossy building blocks with blueish and pinkish parts cut into an L-Shape.
Usually placed as stairs they will smooth a player character's movement up and down gradients. 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.
They are part of a whole "set" consisting of many shapes for Dark Lumite Walls, Light Lumite Walls and regular Lumite Walls that was chosen to be the winner of the second "Battle of the Block Sets": https://twitter.com/creativersegame/status/1039893815698571271
Dark Lumite Stairs cannot be obtained from any Creatures nor from any common randomly spawning Treasure Chests. Receiving already crafted Dark Lumite Stairs from other players or buying them as part of any Building Kits for Blueprints will not provide you with their according crafting recipe.
Dark Lumite Stairs can be crafted in your Crafting Menu (to be opened by typing "Q" as the default key), but only after the according crafting recipe has been unlocked for free by obtaining natural cubic blocks of Dark Lumite Wall.
You can unlock the crafting recipe for Dark Lumite Stairs in your Crafting Menu by:
- crafting or obtaining at least one block of Dark Lumite Wall
4 Dark Lumite Stairs at a time can be crafted from:
- 2 Lumite Slabs that can be made from a Lumite bar by putting it into a Processor. Lumite bars are made from Lumite Ore in a Forge after the Ore has been extracted from Lumite Nodes on the Corruption layer deep underground
- 1 Diamond Rod that can be made from a Diamond bar in a Processor. Diamond bars are made from Diamond Ore in a Forge after the Ore has been extracted from Diamond Nodes that can be found on the Lava layer underground or created by players
- 2 purple Globs of Goo that can be made from Purple Blocks of Goo in a Processor. Common green Globs of Goo cannot be used. Purple Blocks of Goo can be crafted after their recipe has been unlocked for free by crafting green Blocks of Goo
No crafting recipe has to be unlocked for that. Simply carry crafted Dark Lumite Stairs in your inventory/bag or in any quickslot and then activate a Processor that has been placed into the world by looking at it and clicking your right mouse button or typing "f" as the default key.
You can place Dark Lumite Stairs into the game world just like they are, like any other type of crafted block, by putting (a stack of) them into a slot of your quickbar, selecting this quickslot by number or scrolling and then clicking your right mouse button while pointing at the spot where you want to place them.
Stairs will smooth player characters' movement up and down gradients so that no jumping is necessary. They can be placed as projections of walls or for decorative purposes too when being rotated.
Dark Lumite Stairs can be rotated in all directions by holding "R" (as the default key) and moving the left mouse button. The chosen rotation angle can then be "locked" too by simply typing "r", so that all items of the same stack will be placed facing the same direction.
You won't need to equip any Power Cells to pick up Dark Lumite Stairs that have been placed. Of course you won't be able to pick up such half-sized blocks on game worlds, on player claims or in Adventures where your Permission rank is not sufficient (mainly when you are merely a visitor), which can only be changed by the owner of the game world, the respective claim owner or Adventure creator.
Dark Lumite Stairs can also be put on display in Flower Pots, Wood Planters, Stone Wall Shelves, Hidden Temple Altars, Placemats, Galactic Grav-Chambers, Frozen Container, Snow Buried Containers and the like, which will usually reduce them in size.
