The Nightmare of Ashihama, often referred to as The Nightmare, is a boss monster located in Morytania. The Nightmare can be found in the Sisterhood Sanctuary under the town of Slepe. Access to Morytania is the only requirement for fighting The Nightmare.

Upon starting the fight, players are transported to a dream world, where the fight arena takes on a different appearance containing various Eastern motifs such as Torii gates.

While The Nightmare can be fought in groups alongside other players, there is a stronger version called Phosani's Nightmare that can only be fought solo.

Drops from the boss include inquisitor's armour, a set of crush-based armour which improves with crush weapons, especially with the inquisitor's mace, the strongest one-handed crush weapon in-game, and the Nightmare staff, a one-handed staff that can autocast ancient magicks. The staff can be further upgraded with a volatile, eldritch or harmonised orb, each one of which provides a unique effect in combat.

Ironmen are eligible for drops from The Nightmare when defeating it alongside other players. Group ironman players will lose their prestige upon completing an encounter they started with a player outside of their group.

The Nightmare's true origins are unknown, but according to a legend in Ashihama, it was told that an ancient ritual was performed by several shamans, birthing an otherworldly horror that took on the appearance of a large, hag-like woman.^[1] For as long as the sirens of Ashihama can remember, The Nightmare has plagued them, their dreams stolen and feasted upon.^[2] These shamans appeared to have attempted to fight off The Nightmare, eventually culminating in the creation of four totems that could channel power to stop her, but the shamans were wiped out before they could use them on her.^[3]

The Nightmare resided in the caves underneath Ashihama, thus making the sirens wary of entering them in the event they would stumble into her.^[4] One brave siren, Shura, went into the caves and recovered the four totems, allowing her people to fight the Nightmare.^[5] Driven out of Ashihama, it fled west to the mainland, eventually arriving in the Morytanian town of Slepe. While most of the sirens were content with the Nightmare gone from their lands,^[6] Shura continued to pursue it as she wanted to make sure it would be defeated for good.^[7]

The Nightmare arrived at an opportune moment, with the town suffering from the Sleeper Plague as a result of vampyre machinations due to a critical shortage of blood for their growing society.^[8] The Nightmare began feasting from the victims of the plague and began growing more rapidly than she did on Ashihama.^[9] Shura managed to contain her in the centre of the Sisterhood Sanctuary and sought adventurers to keep the Nightmare's powers in check.^[10] Despite their efforts, the Nightmare eventually manifested into Phosani's dreams,^[11][12] though it would also be kept in check by Sister Senga and other adventurers.

The quickest methods of reaching Slepe, where The Nightmare resides, are:

• Teleporting to the Sisterhood Sanctuary via Drakan's medallion after the Slepey tablet has been acquired from Phosani's Nightmare
• Teleporting to Ver Sinhaza via Drakan's medallion, then running north. Once players pass the small dock, they can run east to arrive at Slepe. From there, the player can go down the stairs in the small building directly south of the graveyard, and then run east to arrive at the bridge to the Sisterhood Sanctuary.
• Teleporting to the Hallowed Sepulchre with a Hallowed crystal shard (can be purchased from Mysterious stranger for 1 Hallowed mark) after completion of Sins of the Father, then running to the shortcut on the east side of the city (requires 63 Agility and two long ropes to unlock). Players can then run east to Slepe, where they can go down the stairs as mentioned above.
• Using the Ectophial to teleport to the Ectofuntus, then heading north to the small dock and paying Andras 10,000 coins to row to Slepe. The player will arrive at a dock just south-west of Slepe. Players may also pay Andras a one-off fee of 1,000,000 coins to gain permanent access to his boat for free.
• Using Morytania legs 3 or 4 to teleport to Burgh de Rott, running east to the small docks and then taking the boat to Slepe. This requires partial completion of Sins of the Father, but costs no money.
• Fairy ring code ALQ then run south-east.
• Fenkenstrain's castle teleport tablet, then run south-east.
• Spider cave teleport, then run south-east.

The following official worlds are assigned to The Nightmare:

World	Location	Members	Activity
337	United States (east)	1	Nightmare of Ashihama
514	United Kingdom	1	Nightmare of Ashihama

To begin the fight, approach The Nightmare's unconscious body and select the Disturb option. Players may join in the following 30 seconds before the fight begins: afterwards, players must wait until the fight is over (with The Nightmare or all the players defeated) before they may join.

Unlike most boss fights, The Nightmare's health and combat stats scale to the number of players in the fight (ranging from 5–80 players), though it may be fought in smaller team sizes. The minimum durability of her shield is 2,000 and caps at 19,600. If the Nightmare is floating in the centre rather than lying on the ground, it is an indication that she is fighting a group of players; the symbols on the ground also indicate the phase she is in.

The fight against the Nightmare consists of three phases, all three of which involve the player(s) breaking down its shield sufficiently before they can charge the four totems in the corners of the arena, unleashing a magical blast that deals massive damage to her. In each subsequent phase, the Nightmare will change its special attacks. Once the totems are charged a third time, the Nightmare will be defeated, ending the encounter.

The Nightmare's melee attack ignores accuracy and always hits. In addition, players take 20% of her base damage if using Protect from Melee, and 120% of her base damage if using the incorrect protection prayer. If the Nightmare has very low combat stats, her max hit will be at least a random number between 1-6, subject to the effects of prayer. The Nightmare's defence can be lowered down to a minimum of 120,^[13] however, she restores drained stats at a rate of 20 per minute.

If the player dies while fighting the Nightmare, they will be placed by the Pool of Nightmares and must reclaim their items from Shura. This is a flat 60,000 regardless of carried wealth.

The following money making guide is available for The Nightmare:

Every player in the fight who reaches the minimum damage threshold (which requires dealing damage to both The Nightmare's mental shield and the totems) will be eligible to receive a drop, with the quantity increasing based on how much damage they have done.

The player who deals the most damage in the fight will receive big bones and 10% additional non-unique loot. Additionally, when unique drops are rolled, a weighting system based on damage dealt determines which player will receive it. Players eligible for a unique drop will receive regular bones as a drop.

Drop rates are estimated based on 251,259 samples from the Drop Rate Project, unless otherwise cited.

	Item	Quantity	Rarity	Price	High Alch
	Big bones	1	Always[d 1]	314	0
	Bones	1	Always[d 2]	39	0

With each kill, The Nightmare has a chance to roll two unique drop tables, one containing the armour, mace, and staff, and one containing the orbs; both table rolls can be successful with each kill. The armour, mace, and staff drop table has a 1/83.33 chance to roll, and the orb drop table has a 1/320 chance to roll (with an effective chance of 1/66.67 to get any item).

Additionally, there is a chance that both are rolled a second time (independent of the first rolls), with this chance being (partySize−5)%, clamped between 0 and 75 percent (with party size-related improved drop rates capped at 80 players^[14] (meaning that with a full 80 member party, the armour, mace, and staff drop table has a 1/68.6 chance to roll and the orb drop table has a 1/343 chance to roll, or ~1/57.2 for either).

• If a player spends too long in The Nightmare's dream without sufficient activity they will be removed from the fight. This will be accompanied by a chat message 'The Nightmare grows tired of your poor effort and removes you from her dream.'.
• Prior to The Nightmare's release, two teasers were silently released in an update on 16 January 2020:
  • Sleepwalkers spawned in various locations, and made their way to the entrance of the Sisterhood Sanctuary, where they would climb down (but actually despawn).
  • If a player died anywhere (except a PvP death), there is a 10% chance that a ghostly face of The Nightmare would rise.
• A unique drop from The Nightmare, the siren's charm, which is used alongside a mage's book to create the Siren's tome, initially passed The Nightmare of Ashihama poll. However, a decision was made a day after the poll closed to withhold it from being released into Old School RuneScape, due to continued concerns on how it would devalue the arcane spirit shield.^[15]
