Kraken
Combat level 291 · 255 hitpoints
The most AFK boss in the game. It cannot move, has no special attacks, and only uses magic. The Trident of the seas and Kraken tentacle drops make it a staple mid-game money maker.
Requirements
- 87 Slayer
- Cave kraken task
- Fremennik Slayer Dungeon
Pointers
- Protect from Magic and you take almost nothing. This is a genuinely AFK boss.
- Disturb the whirlpool to start; four tentacles spawn first and must be killed (or ignored if you tank).
- It has enormous MELEE and RANGED defence but very low MAGIC defence. This is the whole reason magic is mandatory.
- A Trident of the swamp/seas plus Occult necklace is the classic setup; a Sanguinesti staff makes it fully AFK by healing you.
- Bring an Ectophial or house teleport. The walk back is the only real time cost.
What the sim brings here
Every worn slot and every inventory row below is the combat simulation's own output, at the style it ranks fastest for each account tier. Each line carries the channel that chose it: sim means the model solved it, and inherited means the value came through from the hand-authored loadout the solver starts from. Riding through a generator does not make a value derived, so those are marked rather than presented as the model's answer. A line marked unattributed carries a channel the model's own vocabulary no longer declares, so no word is put on it at all rather than one being read off the channel's spelling. Where the model has not answered a row, its own refusal is printed instead; where it has answered a row it doubts, the answer is printed with the doubt attached rather than withheld.
max tier, magic (Magic is fastest)
Worn gear: 11 of 11 slots chosen by the sim.
- Head: Ancestral hat sim
- Cape: Imbued guthix cape sim
- Neck: Occult necklace sim
- Ammo: nothing sim
- Weapon: Tumeken's shadow sim
- Body: Ancestral robe top sim
- Shield: nothing sim
- Legs: Ancestral robe bottom sim
- Hands: Confliction gauntlets sim
- Feet: Avernic treads (et) sim
- Ring: Magus ring sim
The model doubts this gear (tied with an identical item, so enumeration order decided): the head, cape, neck, body, legs slots each hold an item the model cannot tell apart from an alternative the search could equally have taken, re-scored identical in this row's own bag. Enumeration order decided it, so the sim had NO REASON; that is not the same as the pick being wrong. SOLVED_GEAR_TIES names them.
Inventory: 5 of 7 rows chosen by the sim, 2 carrying no channel at all.
- Law rune sim
- Fishing explosive ruled
- Saradomin brew(4) x7 sim
- Ancient brew(4) x7 sim
- Cooked moonlight antelope x8 sim
- Rune pouch sim
- Max cape ruled
Spellbook: Standard, claimed by High Level Alchemy (a purpose the boss page names). Grants High Level Alchemy. Cannot cast Vengeance. Vengeance is on Lunar and High Level Alchemy (utility) has claimed Standard. One book per trip.
Open question, not a ruling: Shane: whether runes the page tells the player to carry (alching, telegrab, a mechanic closer) outrank a thrall or Vengeance the damage model ranked on value, when the two live on different books. Default (a) utility wins, chosen by the session-53 coordinator, 2026-09-14, pending Shane
Trip: about 394.65 kills in 157 minutes, limited by food.
mid tier, magic (Magic is fastest)
Worn gear: not answered. needs 87 Slayer to attack; a mid account has 80. No mid account can start this fight, so no loadout is solved for this tier. The max tier can.
Inventory: not answered. the gear solver refused this row (slayerLocked), so there was no loadout to build a bag around and this generator was never handed the row. Its words: needs 87 Slayer to attack; a mid account has 80. No mid account can start this fight, so no loadout is solved for this tier. The max tier can.
budget tier, magic (Magic is fastest)
Worn gear: not answered. needs 87 Slayer to attack; a budget account has 80. No budget account can start this fight, so no loadout is solved for this tier. The max tier can.
Inventory: not answered. the gear solver refused this row (slayerLocked), so there was no loadout to build a bag around and this generator was never handed the row. Its words: needs 87 Slayer to attack; a budget account has 80. No budget account can start this fight, so no loadout is solved for this tier. The max tier can.
What each of those badges means
- derived:ascent (sim): an accepted coordinate-ascent move: betterThan() preferred this candidate over the incumbent under the row objective and band. The weapon+ammo+shield pairing and the crystal set arrive here too, because both are offered to the same acceptance test.
- derived:composed (sim): balanceInventory() sized this row from the derived supply menu. The menu enumerates CONSUMABLES and narrows by style, tier and price; it is not the authored bag.
- derived:empty (sim): the finished loadout leaves this slot EMPTY, and that is an ANSWER rather than a gap: a two-handed weapon forfeits the shield and a weapon that stores its own ammunition frees the ammo slot. Recorded so a null slot is never read as unprovenanced.
- derived:pouch (sim): derivePouchInto(): the rune pouch and its loose overflow, from the spell the build actually casts and the pouch slot criterion. Not from a pouch a human typed.
- ruled:escape (ruled): escapeLeg(): the way OUT, taken from the typed per-tier table ESCAPE_PLAN and judged against the account, with nothing substituted and no fallback ladder. The ACCOUNT CHECK is a derivation; the CHOICE of item is not, so this is not a `derived:` channel. ESCAPE_PLAN carries no attributedTo field (PROVENANCE_BACKLOG: silent-and-unattributed), so this channel does not claim one either.
- ruled:fightStart (ruled): fightStartPlan(): an OPTIONAL fight-start item the boss or strategy page recommends (the sentence and its no-item alternative ship on the plan), carried on Shane's 2026-09-15 ruling that such an item is ALWAYS carried, even at a supply cost. The item is read from the page; the decision to carry it is the ruling, not a derivation.
