OSRS Boss Gear & Inventories

The Nightmare

Combat level 814 · 2400 hitpoints

The Morytania group boss. Drops the Inquisitor's set, Nightmare staff and the Harmonised/Volatile/Eldritch orbs. Fought in a group; Phosani's Nightmare is the solo-only harder variant.

Requirements

• Sins of the Father
• ~90+ combat
• 70+ Prayer
• Team recommended (scales with players)

Pointers

• She cycles Melee / Ranged / Magic attacks. Everyone flicks prayers together.
• Totems: five totems around the arena must be charged to progress the fight; the Nightmare becomes immune otherwise.
• Sleepwalkers spawn and walk toward the totems. Kill them before they arrive.
• Parasites burrow into players and must be killed by the group; they explode for heavy damage.
• Her "shadow" AoE covers a wide area. Move to a clean tile.
• She is weak to CRUSH, which is why the Inquisitor's set she drops is the ideal gear for her.
• MAGIC DAMAGE AGAINST THE TOTEMS IS DOUBLED. In a team, whoever is charging totems should be casting, not swinging. This is the single biggest speed lever in the fight.
• Sleepwalkers are cleared fastest with Blood Barrage or a Saradomin godsword spec.

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.

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: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:travel (sim): travelPlan(): the way IN, ranked out of the derived transport graph against this account's own unlocks, rather than copied from whatever a human typed. The way OUT is a separate channel (`ruled:escape`) because it is a typed choice, not a ranking.
• 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.
