Nechryarch Guide

Bosses guide · Updated September 2025

The Nechryarch is the greater demon superior boss - a bigger version of the standard nechryael that spawns bursting adds and hits harder through the fight. The teleport lands at 3405, 9972, 3 up on the third level of the Catacombs of Kourend.

It is the imbued-heart source: the magic-boosting drop that only comes from the superior nechryael.

The fight

Nechryarch attacks with a magic-based burst - pray magic and most of the damage is covered. The real mechanic is the death spawn adds: it summons small bursting creatures mid-fight that pop on death or on a timer, dealing free damage unless you kill or dodge them.

Burst the adds fast or the chip damage compounds - the boss itself is simple.

Gear

  • Protect-from-magic - the whole fight is one style.
  • An AoE or fast-swap weapon for the bursting adds.
  • The catacombs are multi - expect stray demons joining in.

The drops

The imbued heart is the signature - plus the standard nechryael table of rune items, seeds, and noted supplies at volume. Every tradeable drop is GE-linked below.

Efficient farming notes

He is a slayer-adjacent boss - you can roll him as a nechryael task target, which means a slayer assignment doubles as a Nechryarch hunt. The catacombs multi-combat status helps here: other demons joining the fight speed up the kill rather than threaten it.

Because the fight is single-style with a simple add mechanic, he is one of the better semi-AFK wildy-adjacent farms - pray magic, watch for the adds, and the kills accumulate.

  • Slayer assignment on nechryaels makes him a double-duty target.
  • Clear death spawns instantly - they pop for free damage.
  • A cannon is dead weight in multi; kill the adds by hand.

The imbued heart grind

The imbued heart is the chase drop - a useable item that temporarily boosts magic levels, and the only source is superior nechryael-type bosses. It is a rare roll, so most kills pay out in the standard table instead: rune items, noted supplies, and herbs at volume.

Because the catacombs spawn him intermittently while you slay, half of Nechryarch farming is just doing your nechryael tasks and being ready when the superior appears.

When to hunt him

Because he spawns as a superior during nechryael kills, the efficient hunt is indirect: take nechryael tasks from the slayer master, kill them in the catacombs, and treat each Nechryarch as a bonus boss inside your task.

The catacombs are also where dark totem pieces drop for Skotizo, so a nechryael grind simultaneously builds toward two bosses at once.

Session summary

Take the nechryael task, kill demons in the catacombs, and let the superior spawn come to you - the imbued heart is the prize, and the table keeps the grind profitable while you wait.

The catacombs bonus

Every kill in the catacombs also drops dark totem pieces and ancient shards toward Skotizo and the Kourend content - Nechryarch farming is really a three-birds-one-stone grind: slayer XP, heart rolls, and totem progress.
