nether-entry

# Skill: nether_entry Phase 2 of the dragon route. Build a portal, ignite it, walk through. Actual Nether survival starts in `blaze_rods`. ## Done when - A lit Nether portal stands at a known overworld location (**report its coordinates to your owner** — it's the way home) - You are standing in the Nether with the packlist below intact ## Obsidian (need 10) Mine it from a **ruined portal** — a structure that's just standing obsidian, no lava-casting. This is the only route: casting your own (water over lava) leaves every fresh obsidian block touching lava, and I refuse to mine fluid-adjacent blocks (it would flood or burn the dig), so a cast wall is unminable by design. 1. `locate.structure("#minecraft:ruined_portal")` — searches the whole family and returns the nearest. **Skip `ruined_portal_ocean`** (underwater) if the result names it; re-search or pick a land one — I can't dive. 2. `gear.wear("diamond_pickaxe")` (obsidian needs diamond), `move.goto_` the portal coordinates. 3. `scan.blocks("obsidian", {into = "portal"})`, then `move.goto_("portal", {arrive = "dig"})` and `work.dig("portal", {count = 10})` — it digs the frame's obsidian within its reach; `work.collect` the drops, and repeat the three while `area.has("portal")`. ~9.4s per block is normal. Notes: - A portal's frame mixes plain **obsidian** with **crying obsidian** (purple particles). Crying obsidian is a *different block and useless for a portal frame* — a scan for `obsidian` alone leaves it out, so a single portal may yield fewer than 10. If you come up short, `locate.structure("#minecraft:ruined_portal")` again for the next nearest and top up. - If `work.dig` reports obsidian that "can't be broken here" with fluid beside it, that portal sits in a wet/lava pocket — relocate to a cleaner one rather than fighting the fluid. ## Portal build - Frame: 4 wide × 5 tall, **corners omitted = exactly 10 obsidian**, standing vertically. Inner opening is 2×3 air. - Pick flat ground near your base. Write the frame as a small design — two side columns of 3 plus top and bottom rows of 2 — and build it in one go; a single `build.set` handles any one-off correction: ``` build.new("portal") build.line({x = 0, y = 1, z = 0}, {x = 0, y = 3, z = 0}, {block = "obsidian", into = "portal"}) build.line({x = 3, y = 1, z = 0}, {x = 3, y = 3, z = 0}, {block = "obsidian", into = "portal"}) build.line({x = 1, y = 0, z = 0}, {x = 2, y = 0, z = 0}, {block = "obsidian", into = "portal"}) build.line({x = 1, y = 4, z = 0}, {x = 2, y = 4, z = 0}, {block = "obsidian", into = "portal"}) build.raise("portal", {at = {x = 120, y = 64, z = -35}}) ``` - **Flint & steel**: craft `flint_and_steel` = 1 iron ingot + 1 flint, a 2×2 recipe (`inv.craft` it; see the `containers` skill to lay a grid by hand). Flint drops from gravel you `work.dig`, ~10%/block. - **Ignite**: `use.block({x = 121, y = 65, z = -35}, {item = "minecraft:flint_and_steel"})` aimed at an **empty air cell INSIDE the frame** (a bottom one), not at the obsidian. The fire lands in that cell and the portal forms. - Enter: `move.goto_` the portal cell and stand in it until the dimension changes (`status.self` confirms). ## Packlist (verify with `status.self` before igniting) | Item | Qty | Why | |---|---|---| | Cooked food | 32+ | Your healing | | Diamond sword + bow | 1 + 1 | Equip for combat only — hold the pickaxe while travelling (navigation digs with the held tool) | | Arrows | 32+ | `fight.attack` spends them only on what it cannot reach (~6 per blaze); run low → carry extra food and let it melee | | Diamond pickaxe (+ iron backup) | 1 + 1 | Obsidian, digging | | Cobblestone | 64+ | Throwaway blocks for navigation — bridging lava lakes eats it; keep it on your `throwaway` list | | Gold helmet (worn) | 1 | Piglin truce; 5 gold ingots if you must craft one | | Flint & steel | 1 | Re-light the portal if a ghast blows it out | **Never place or use a bed in the Nether — beds explode there.** ## Nether ground rules - **Don't dig straight down**; lava oceans sit under most terrain. Navigation bridges lava when it must — keep cobblestone stocked. - **Water doesn't exist here**: buckets won't place. - **Zombified piglins are pacifists until hit — and then they ALL swarm.** Never `fight.attack` them. - **Ghasts** snipe from far; their fireballs can break the portal. On arrival, note the Nether-side portal coordinates (`status.self`) and report them to your owner. Overworld↔Nether coordinates map 8:1 horizontally. ## What to load next Standing in the Nether, packlist intact → mark phase 2 `completed`, `skill.load("blaze_rods")`. Load `combat_basics` too if you haven't — blazes are the first real combat test.
