You have a few options. 1. Buy it in the server shop! 2. Go to a cave and dig it up in a lava pool! 3. Create an impossible to create Obsidian generator (new Minecraft physics laws have decided to break the Obsidian generator) 4. There is a place where there is more Obsidian than anywhere else in Minecraft. You should know! 5. Wait till 1.17 they have surprises for you here. # Strategy: Checkerboard pattern If obsidian is expensive, and you want the most efficient way to defend your base with it, the chequerboard pattern strategy might be suitable for you. ##### Example design of Obsidian wall.

So by all means build your base and try to defend it with water flowing over it, you will be raided. Trust me.
