The Checkered Obsidian Wall is a nearly black dark-blue building-block with a debossed pattern of 9 squares on it on all 6 sides.
It can be crafted in your Crafting Menu (default key "q") after the according crafting recipe has been unlocked upon buying it in the Store as a part of the "Decorative Obsidian Pack". You cannot obtain the crafting recipe in any other way.
To craft 8 (blocks of) Checkered Obsidian Walls, you'll need:
- 2 Obsidian Slabs made of Obsidian (bars) in a Processor
- 1 Glob of Goo made from Mold in a Processor or occasionally looted/pet-harvested from many Creatures
- 2 Iron Rods made of Iron Bars in a Processor. Iron Ore can be extracted from Nodes on the Stalactite layer underground, or found in Iron Treasure Chests or in Diamond Treasure Chests
The "Decorative Obsidian Pack" itself also includes 99 already crafted blocks of Checkered Obsidian Walls additionally to the crafting recipe. These blocks can be claimed on one gameworld of your choice once.
Please note that you can only pay in the Store with Coins that can be purchased via Steam Wallet (also via Store). All crafting recipes bought in the Store are automatically permanently added to the crafting menu (and already unlocked), and will always be available on all Creativerse gameworlds, even those that have the world option "world bound recipes" enabled.
