Skyblock Survival Rules

Start on a tiny floating island. Initial resources: 1 tree (wood+sapling), 1 lava (cobblestone generator+fuel), 1 dirt, 1 ice (melts to water). Expand the island, acquire new resources, build automation. Classic goal: from nothing to a sky empire.

Seed: i (single letter, Bedrock 1.21). Spawns on 3x3 grass floating island at Y=100. Adjacent island with 1 oak tree. Lava 15 blocks below. Scout in Creative, then switch to Survival.

Warning: First priority: infinite cobblestone generator (lava+water). Then infinite water source (2x2 pool). Step by step automation from there.

Island Expansion Steps

① first tree -> saplings xN to keep wood flowing; ② lava+water infinite cobble generator (source of all stone); ③ 2x2 pool for infinite water; ④ expand platforms with cobble+soil; ⑤ fishing/village trades for food; ⑥ mine iron for armor. Steady steps, don't rush.

Warning: Standard cobble generator: dig a 1x3 trench, pour lava at one end, water at the other — the middle block yields cobble steadily.

Automation Roadmap

Once fed: ① kelp farm -> fuel+food; ② sugar cane+books -> enchanting books; ③ breed villagers -> trade for diamonds; ④ mob farm/crop farm. Goal: evolve from hand-crafting to passive output. Use the SkyBlock Classic template as a reference progression.

Warning: Skyblock has no natural mobs — a mob farm needs its own dark platform + water streams to spawn anything.
