| description | Acquire obsidian, build a Nether portal with build, ignite it with flint & steel via interact_at, and enter the Nether with the right packlist. |
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.
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.equip_item(diamond_pickaxe) (obsidian needs diamond), goto the portal coordinates.mine(obsidian, 10) — it digs the frame's obsidian on its own. ~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 —
mine(obsidian) already ignores it, 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
mine reports it skipped blocks "against water or lava", 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. Build the frame with one
build call: two side columns of 3, plus top and bottom rows of 2. Use place_block only for a nearby single-cell correction.
- Flint & steel: craft
flint_and_steel = 1 iron ingot + 1 flint, a 2×2 recipe (lookup_recipe + transfer into your own grid; see the containers skill). Flint drops from mine(gravel), ~10%/block.
- Ignite:
interact_at(button=right, x, y, z, item_id=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:
goto the portal cell and stand in it until the dimension changes (get_self_status confirms).
Packlist (verify with get_self_status 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+ | ranged_attack consumes them (~6 per blaze); run low → switch to melee + extra food |
| Diamond pickaxe (+ iron backup) | 1 + 1 | Obsidian, digging |
| Cobblestone | 64+ | Navigation scaffold — bridging lava lakes eats it |
| 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
melee_attack them.
- Ghasts snipe from far; their fireballs can break the portal. On arrival, note the Nether-side portal coordinates (
get_self_status) 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, load_skill(name="blaze_rods"). Load combat_basics too if you haven't — blazes are the first real combat test.
