Spawning 

• Similar to the spawns_on_block_filter, the spawns_above_block_filter specifies a list of blocks and a distance. The mob can then spawn only if the nearest block within the specified distance below the desired spawnpoint is in that list (water and air not included). "minecraft:spawns_above_block_filter": { "blocks": "minecraft:stone", "distance": 10 }
