# Skill: dragon_combat Phase 6 — the final boss. The Ender Dragon has 200 HP and heals from the end crystals while any survive. Mistakes here cost the whole run, mostly via the void. ## Done when The dragon's HP reaches 0: death animation plays, ~the exit portal opens in the central bedrock fountain, a dragon egg appears on top. Tell your owner congratulations. ## Packlist (verify with `get_self_status` BEFORE entering the portal) - Diamond sword + bow, **32+ arrows** (10 crystals + air shots + misses) - **128+ cobblestone** — the spawn platform is often ~100 blocks from the island and navigation bridges the gap with your blocks - **32+ cooked food**, plus a golden_apple if you have one (emergency heal) - Armor on, sword in hand (`get_self_status` to confirm) ## The arena - You arrive on a small obsidian platform out in the void. The **central island** (end stone, Y≈60) holds everything; `goto` toward (0, 62, 0) — navigation bridges across. **Falling into the void destroys you and everything you carry.** Fight near the island centre, never at the rim. - **10 obsidian pillars** ring the centre, each topped by an **end crystal**. The 2 tallest crystals sit inside iron-bar cages. - Intact crystals continuously heal the dragon — damaging it before they're gone is wasted effort. **Crystals first, always.** ## Step 1 — the 8 open crystals Carry a bow with arrows, then `scan_nearby_entities` → `attack({"entity_ids":[crystal_ids]})`. Crystals die to one arrow and **explode with twice a creeper's power**, so `attack` refuses to close on one at all: it holds 12 blocks off and shoots. Without arrows it reports them unreachable rather than walking into the blast — that is the tool working, not failing. ## Step 2 — the 2 caged crystals Per caged pillar: 1. `goto(pillar_top_x, top_y + 1, pillar_top_z)` — navigation pillars up the side on its own (this is what the spare cobblestone is for). 2. `mine(iron_bars)` to open the cage. 3. `goto` back down/away, then scan that crystal and call `attack({"entity_ids":[id]})` — it keeps its own distance from there. While you're up high, the dragon may strafe the pillar — if `get_self_status` shows falling HP, finish the bars and get down first. ## Step 3 — kill the dragon Two modes, alternating: - **Flying**: scan the dragon runtime ID, then `attack({"entity_ids":[id]})` — out of reach means it shoots. Head shots take full damage, body shots are reduced; accept slow progress. - **Perched** (it lands on the central fountain periodically, more often at low HP): the same `attack` call now reaches it and swings — the melee window does the real damage. Back off (`goto` 10+ blocks sideways) when it takes off again. ### Its attacks and your answers | Attack | Effect | Answer | |---|---|---| | Dive/charge | ~10 dmg + heavy knockback | Stay near the island centre so knockback can't reach the void | | Dragon's breath | Lingering purple cloud, ~3 dmg/s | `goto` sideways immediately; **never stand or fight in purple** | | Wing buffet (perched) | ~5 dmg + knockback | Expected cost of the melee window; eat between perches | ### HP discipline This is a long fight. Between every tool call: `get_self_status`; **HP ≤ 10 → disengage to centre, `eat_item`, only then re-engage.** The dragon doesn't rush you — patience is free, death isn't. ## After the kill - The exit portal (bedrock fountain, centre) returns you to the overworld spawn — `goto` into it when your owner is ready. - The dragon egg on the fountain is a trophy your owner may want; it teleports when punched, so leave its extraction to them. - Mark the entire endgame plan `completed` in `todowrite`. ## If you die Your run ends where your body fell. If your owner recovers your gear, re-verify the packlist (`get_self_status`), reload this skill, and walk back in through the still-active stronghold portal — the dragon keeps whatever damage it already took.
