The Phantom Muspah is a solo boss that can be fought after completion of the quest Secrets of the North. It is the leftover energy of the Strange Creature that manifested after the events of the quest.

The Phantom Muspah is stronger than its quest variant, but otherwise shares the same attacks and mechanics. All forms of the Phantom Muspah have 33% freeze resistance, meaning it will only stay frozen for 66% of the base freeze duration of ice spells.

Unique drops from the boss include ancient essence, used in the creation of forgotten brews or upgrading the imbued heart into a saturated heart, and the venator shard, of which five of these can be combined to create the venator bow, a unique bow that shines in multicombat situations.

If players die against the Muspah, their grave will appear outside the lair in the Ghorrock Dungeon. When the Muspah is defeated, it will respawn after 30 seconds.

A scoreboard by the crevice shows statistics related to the Phantom Muspah.

Fight overview

The Phantom Muspah alternates between a ranged form and a melee form roughly every 100 damage in ranged form and 80 damage in melee form that it takes. In its range form it spits green ranged projectiles, is weakest to ranged, and occasionally charges a powerful magic attack. The magic attack can hit up to 72 and applies corruption which drains prayer over time, but is fully blocked by quickly switching to Protect from Magic. In its melee form it uses melee attacks that deal increasingly more damage the longer the Muspah stays still, even through prayer. In this form it is weakest to magic, and must be frozen or kited around.

When changing forms it spawns a few spikes around the arena including one under the player, which should be dodged or else it will knock the player aside and heal the Muspah based on damage dealt.

It has two special attacks that it uses at 637 (75%) and 425 (50%) health. If it spawns in ranged form it uses Lightning Clouds first, otherwise it uses Homing Spikes first.

Lightning Clouds - The Phantom Muspah will rapidly teleport around the arena, leaving behind lightning clouds that travel across the area, which also must be avoided.
Homing Spikes - The Phantom Muspah will slam the ground, causing 1-4 spikes to slowly home in on the player for ~20 seconds.

A player fighting the Phantom Muspah.

Upon reaching less than 127 health, the Phantom Muspah will teleport to the centre of the arena and unleash a massive shock wave that must be avoided by standing behind a spike. It then activates a prayer shield; during this shielded phase it attacks similarly to its ranged phase, along with use of the overhead Soul Split prayer and summoning additional spikes that appear under the player. The shield should be drained via using Smite in between its attacks, and/or using enchanted sapphire bolts.

After the shield is depleted it will return to its ranged form. Every four attacks, it will generate spikes onto the arena, and players must defeat it as quickly as possible or the entire arena will be covered in spikes.

Changes

Date	Changes
22 July 2026 (Update)	The duration of the boss' Homing Spikes attack has been decreased from 50 ticks (30s) to 34 ticks (20.4s). The boss' Homing Spikes will now end upon entering its shielded form. The boss, upon switching forms for the first time, will subsequently swap forms only after it has taken four separate instances of damage by the player (in addition to the existing damage thresholds).
6 August 2025 (Update)	The bone dagger's special attack now correctly guarantees a hit against the Phantom Muspah when used on the first hit.
25 June 2025 (Update)	The Phantom Muspah now has a 65% elemental weakness to wind spells. The 10/220 drop of 28 noted manta rays has been replaced with a 10/235 chance to roll a table containing raw sharks, cooked manta rays, and shark lures. The amount of soul runes dropped was lowered from 466 to 380. The amount of grimy toadflax dropped was lowered from 55 to 40. The amount of torstol seeds dropped was lowered from 4 to 2. The drop rate of smoke runes increased from 10/220 to 15/235 The drop rate of molten glass increased from 10/220 to 15/235 The drop rate of water orbs increased from 10/220 to 15/235
24 July 2024 (Update)	The amount of steel cannonballs dropped has been increased from 666 to 670.
18 April 2023 (Update)	The Phantom Muspah's overhead for Soul Split was updated to use the Ruinous Powers colour scheme.
1 March 2023 (Update)	Combat Achievements were added for the boss.
15 February 2023 (Update)	A bug was fixed where the Phantom Muspah's Freeze duration reduction was applying twice.
25 January 2023 (Update)	The quantity of various items dropped have been reduced slightly.
18 January 2023 (Update)	The ectoplasmator now works on the Phantom Muspah. Monster Examine now displays the boss's defensive stats. The Phantom Muspah's entry in the collection log will now turn green when filled. Returned the original melee dodge mechanic the boss had on release; as a consequence, the 10% ice spell accuracy bonus was removed.
12 January 2023 (Update)	Hotfix A bug in which the boss always hits zero whilst moving towards you while attacking, and having Protect from Melee active, has been fixed. The boss's melee attack is now less accurate with Protect from Melee active. To compensate, the melee attack will now hit through the prayer more consistently. The boss's melee attacks should now be easier to dodge when keeping distance from it. The accuracy of ice spells are now increased by 10% when the boss is not frozen. The boss should now behave more consistently if taken down before the Prayer Shield phase. The quantity of various seeds and herbs have been reduced slightly. The drop rate of supplies has been reduced from 1/3.5 to 1/4.5.

Trivia

In RuneScape, the Muspah are a race of creatures created by the Elder God Mah, as an amalgamation of the most fearsome creatures from her nightmares. In Old School RuneScape, no other Muspah exist in the game, and little is known about the creatures' lore as of yet, but their origin story could likely be similar to their counterparts in RuneScape 3, as evidenced by their examine text (Imagination gone wild.) and the examine text of the Strange Creature (A creature of nightmares.).
The Muspah may have been named after Muspelheim, the land of raging fire in Old Norse mythology.
Physical similarities and a previous steel cannonball drop of 666 may be a reference to Diablo II's demon Duriel.
The "scoreboard" plaque across from the entrance contains Morse code that translates to "YOU GOT THIS BUDDY".
