Greater Nechryaels

Combat level 200 · 205 hitpoints

The stronger nechryael, modelled at the Catacombs of Kourend where the burst method lives. The strategy page: "Players who seek a fast task are encouraged to kill them in the Catacombs of Kourend, as fourteen greater nechryael are found in two chambers of seven each. With a goading potion to draw aggression, players will find themselves gaining very high experience rates with minimal downtime."

Requirements

• 80 Slayer
• 85 combat
• Xeric's talisman or a Kourend portal for the Catacombs
• Ice Burst or Ice Barrage on Ancients for the stacked method

Pointers

• MAGIC DEFENCE IS ZERO AND THEIR MAGIC LEVEL IS 1. That is the mechanical reason bursting works here, quite apart from the stacking: a cast against them is close to a guaranteed hit.
• They are DEMONS, so a demonbane weapon applies. The strategy page: "Using a demonbane weapon is highly recommended. These weapons scale extremely well with strength bonus, so it is strongly recommended to prioritise this over prayer bonus gear where possible."
• DEATH SPAWNS PIERCE PRAYER. Up to two per nechryael, max hit 2, and "as they attack with typeless melee, Protect from Melee has no effect on them". They also "are able to attack you in single-combat areas regardless of if you are already in combat".
• Safespotting turns the spawns off entirely: they "will not be summoned if the nechryael is unable to attack the player back".
• They are not aggressive, so something has to pull them. A goading potion is the standard; darts, knives or a Dinh's bulwark are the cheap alternatives.
• Iorwerth Dungeon is the melee answer, and the page says why: the Catacombs are "very likely to be crashed by another player if using melee". Iorwerth is single-way, and those spawns also drop crystal shards.

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: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: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.
