Method and credits
All seeds on Blockaria were found by our own search tool, not copied from other lists. Biomes and structures are computed with cubiomes by Cubitect (MIT licence), a version we froze for 26.1 and 26.2, plus the 26.3 Dappled Forest rule. Coordinates are the starting chunk of each structure (within 16 blocks); heights are confirmed in game. Map: Chunkbase.
