Skill: stronghold_finding

Phase 5 of the dragon route. With rods and pearls in hand you craft eyes, walk straight to the stronghold — `locate_structure("minecraft:stronghold")` replaces the whole throw-and-triangulate ritual — and activate the End portal.

Done when

• You're standing at an activated End portal (all 12 frames filled, purple portal surface visible)
• Dragon-fight gear still intact (get_self_status check against dragon_combat's packlist)

Step 1 — craft the eyes

Both are 2×2/shapeless recipes — lookup_recipe for the layout, then transfer the ingredients into a grid and take the result (see the containers skill; no crafting table needed).

1. blaze_powder — each blaze rod grinds into 2 powder.
2. ender_eye (×12) — 1 blaze powder + 1 ender pearl each.

12 is the worst case; frames generate pre-filled at 10% each (~1–2 typically), so spares may remain. Never throw eyes to navigate — locate_structure("minecraft:stronghold") is free and exact; eyes are only for the frames.

Step 2 — go there

1. locate_structure("minecraft:stronghold") → coordinates, direction, distance (often 1000–2500 blocks; the journey is the long part).
2. goto(x, ~60, z) to cross the surface, then goto(x, 30, z) — navigation digs down on its own. Strongholds sit around Y 6–50.
3. Hit stone bricks → you're inside. scan_blocks(end_portal_frame) to find the portal room; no match → explore corridors with goto and rescan. (Stronghold corridors are stone_bricks / mossy_stone_bricks / cracked_stone_bricks.)

Step 3 — secure the portal room

The room has a lava pool under the frame and a silverfish spawner on the stairs:

1. mine(spawner) immediately — unlike the blaze spawner, this one is pure liability.
2. If silverfish are already out, scan them, then pass their runtime IDs to melee_attack; don't let them burrow into the brickwork.
3. build cobblestone over the lava pool edges where you'll stand.

Step 4 — fill the frames

1. The 12 end_portal_frame blocks ring a 3×3 opening. scan_blocks(end_portal_frame) lists all 12 positions.
2. inspect_block each frame — the has_eye property tells you which are pre-filled.
3. interact_at(button=right, x, y, z, item_id=minecraft:ender_eye) on each empty frame. Eyes cannot be taken back out.
4. The 12th eye activates the portal; the opening fills with the starfield surface.

Before dropping in

• load_skill(name="dragon_combat") now, not after jumping — the fight needs a plan.
• Verify the dragon packlist and tell your owner the portal is active and where it is. They may want to set their respawn nearby and come watch — entering the End is one-way until the dragon dies.
