Demonic Gorillas
Combat level 275 · 380 hitpoints
Crash Site Cavern in Kandarin, 28 spawns. The best non-boss gp/hr in the game and the only source of Zenyte shards (1/300) plus ballista parts. The whole fight is built around forcing you to switch styles.
Requirements
- Monkey Madness II
- Attack 80+, Strength 85+, Defence 80+, HP 80+
- Ranged 85+, Magic 70+, Prayer 70+
- Slayer 69 for tasks (not needed to fight)
Pointers
- THE ADAPTATION MECHANIC IS THE FIGHT: after ~4 hits and 70+ damage it swaps its overhead to your last-used style. Swap weapons the moment it prays against you.
- They use all three combat styles themselves and change attack style after missing three consecutive hits, so you are flicking prayers as well as swapping weapons.
- Boulder special: it throws a rock for 33% of your CURRENT health. Step one tile off the marked spot. Other players' boulders can hit you too.
- They have a 35% elemental weakness to WATER spells, which makes a magic switch surprisingly strong.
- Verac's equipment bypasses their protection prayers entirely (though not their special attacks), a genuine budget strategy.
- A Dwarf multicannon does NOT work on them. Thralls do.
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.
The model declines to name a best style at this encounter: no single style this encounter admits meets its requirement (the monster switches its own protection prayer to the style that last hurt it, so one style stops working partway through every kill; Demonic gorillas/Strategies; Demonic gorillas), so there is no single best style to open on. Every style it has either an answer or a stated reason for is listed below, rather than one being chosen for it.

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:cheapestEqual (sim): cheapestOfEquals(): at budget, an exactly-tied cheaper item replaced the one in this slot. It changes the price and, by construction, not the score.
- 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:obtainable (sim): canonicaliseObtainable(): the finished loadout named a variant the model cannot state a route to, and this pass swapped it for the obtainable equal.
- 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.
- derived:seedWeapon (sim): the weapon the ascent BEGAN from, taken off the dps-ranked weapon shortlist, or the forced weapon of a multi-start seed. Never off a start loadout.
- derived:spec (sim): a carried special-attack weapon PROPOSED by `specPlan` (specchoice.js), which prices every SPEC_ATTACKS weapon that deals damage or drains defence on top of the bag solved without one, and KEPT by `judgeSpecArms` only where the composed bag with it beats the bag without it under `compareScores`. The row's `kpt.specWeapon` carries both arms.
- derived:switch (sim): a carried gear switch, named by `build.switches`, composed by `resolver.hybridSwitches` out of the OTHER styles SOLVED gear (solvedgear.js), at the same tier as the row. This is the derived replacement for `inherited:switch`; the two differ only in which source answered, and the resolver states that per switch rather than letting the consumer infer it.
- 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.
