The short version
30-second read- Totems ignore magic accuracy entirely. They have no defensive stats, so gear for magic damage and skip anything that adds accuracy without raising max hit.
- Drink Sanfew serum before parasites burst. Afterwards is too late; click the Hitpoints orb to drink without shuffling your inventory.
- Always kill the sleepwalkers. If none die, her power blast always kills you, so this is not a fight you win by tanking.
- The Slepey tablet now drops by kill 25. At 1/25 and guaranteed on the 25th kill since 25 June 2025, it unlocks Drakan's medallion straight to Slepe.
Overview
Phosani's Nightmare is the solo-only, harder version of The Nightmare: a combat level 1,024 boss you start by drinking from the Pool of Nightmares in the Sisterhood Sanctuary under Slepe. The only requirement is Priest in Peril for Morytania access. You break her shields with crush melee, charge the totems with magic, and every kill has about a 1/111 chance at a unique: inquisitor's armour, the inquisitor's mace, the nightmare staff or one of three orbs.
She was released on 30 June 2021 and changed a lot on 25 June 2025, when the old opening phase was cut. The fight is now three shield phases and a 150-health desperation phase, so a guide or video from before that date describes an extra phase you will never see.
Two widely repeated requirements are wrong. There is no Slayer requirement, and since the 13 August 2022 update you no longer need a normal Nightmare kill first. The game still shows a one-time warning if your Nightmare kill count is zero, and you can ignore it.
Kills are roughly three times faster than the group version because the health pool is structured differently. Praying correctly fully blocks her standard attacks instead of only reducing them, and the hits you fail to pray land far harder, so your reaction speed decides the kill.
| Detail | Value |
|---|---|
| Combat level | 1,024 |
| Hitpoints (infobox) | 3,200, but the fight is health-gated by shields and totems (see below) |
| Slayer requirement | None |
| Quest requirement | Priest in Peril, for Morytania access |
| Nightmare kill needed first? | No, since 13 August 2022 |
| Solo or team | Solo only, in an instance |
| Weak to | Crush at +40, against slash +180 and stab +120 |
| Death cost | 60,000 coins to Sister Senga |
Requirements and Access
The requirement list is much shorter than its reputation suggests. What actually gates the fight is your ability to react, not your Slayer level.
| Requirement | Detail |
|---|---|
| Slayer | None. This boss has no Slayer requirement |
| Quests | Priest in Peril, for Morytania access. That is the only hard quest requirement |
| Prior Nightmare kill | Not required. Sister Senga has allowed the fight without one since 13 August 2022 |
| Recommended quests | A Taste of Hope for Drakan's Medallion, the fastest travel, or Ghosts Ahoy for the ectophial |
| Suggested stats | 95+ Attack, 95+ Strength, 85+ Defence, 95+ Magic, 95+ Hitpoints, 70+ Prayer |
| Immunities | She cannot be frozen, poisoned, envenomed, or hit by cannons |
The suggested stats are an indication rather than a gate. The fight will let you in far below them; it simply will not let you finish.
Getting There
The fight is in the Sisterhood Sanctuary, a dungeon beneath Slepe in Morytania. You start it by choosing Drink-from on the Pool of Nightmares, on a raised area north of The Nightmare's arena.
The fastest travel is Drakan's medallion straight to Slepe, which is unlocked with the Slepey tablet, itself a Phosani's drop at 1/25 and guaranteed on your 25th kill since 25 June 2025.
Before you have the tablet: the spider cave teleport then run east; the Hallowed Sepulchre with a hallowed crystal shard plus the 63 Agility shortcut; Drakan's medallion to Ver Sinhaza then north and east; or the ectophial followed by paying Andras 10,000 coins.
What the June 2025 Update Changed
Plenty of Phosani's guides and videos predate the Summer Sweep Up combat update of 25 June 2025, and three of its changes, plus one side effect, affect how you plan a trip today.
| Change | What it means for you |
|---|---|
| The first phase of the encounter was removed | Three shield phases of 400 and a 150-health desperation phase. Phosani's Speedchaser and Speedrunner target times were cut by 1:30 to match |
| Slepey tablet raised from 1/100 to 1/25 | Guaranteed on your 25th kill instead of your 100th, so the Drakan's medallion teleport to Slepe comes early |
| You respawn by the Pool of Nightmares | A death no longer sends you to your respawn point, so getting back to Sister Senga to reclaim is quick |
| Side effect: less time to regain special energy | If you spec freely in phases 1 to 3 you will not reach the desperation phase on 100% energy. A surge potion covers the gap |
Two older changes still catch people out. The normal Nightmare kill requirement went on 13 August 2022, and Project Rebalance on 29 May 2024 improved the drop rates, so unique rates quoted from 2023 or earlier are too low.
Recommended Stats
The unusual thing about gearing for this fight is that magic accuracy is worthless against the totems, because they have no defensive stats. Prioritise magic damage and skip anything that only adds accuracy without raising your max hit.
| Stat | Comfortable | Why |
|---|---|---|
| Attack | 95+ | Crush is her weakness at +40 defence bonus, against +180 slash |
| Strength | 95+ | Crush weapons always max hit husks and weakened parasites |
| Defence | 85+ | Her max hits are 73 melee, 80 magic and ranged, and around 85 on the dash |
| Magic | 95+ | For the totems, where only damage matters and accuracy does nothing |
| Hitpoints | 95+ | Off-prayer hits land hard, and the reaction window is 2 to 3 ticks |
| Prayer | 70+ | You are switching protection prayers constantly, not holding one |
Gear Setups: Budget, Mid and Best in Slot
Two setups matter: a crush melee setup for her physical phases and husks, and a magic setup for the totems where you want raw damage and nothing else.
The Wiki notes that the Eye of Ayak and Tumeken's shadow produce similar output despite different speeds and max hits: 70 for the shadow, 44 for Ayak with a fortified Elidinis ward. The real difference is longrange range, 10 versus 8, which matters during Corpse Flowers.
| Slot | Budget | Mid | Best in slot |
|---|---|---|---|
| Melee weapon | Zamorakian hasta or a crush option | Inquisitor's mace | Scythe of Vitur on crush, then the inquisitor's mace, the weapon the fight is designed around |
| Magic weapon | Trident of the swamp | Sanguinesti staff | Tumeken's shadow, or Eye of Ayak with a fortified Elidinis ward |
| Head | Neitiznot faceguard | Inquisitor's great helm | Inquisitor's great helm |
| Body / legs | Bandos | Inquisitor's hauberk and plateskirt | Inquisitor's, or Ancestral for the totems |
| Neck | Amulet of blood fury | Amulet of torture | Amulet of rancour. Blood fury helps a learner but is not something to rely on |
| Ring | Berserker ring (i) | Ultor ring | Ultor ring, listed rank 1 for the melee setup |
| Special | Dragon claws | Burning claws (on stab) or ornate granite maul | Crimson kisten, then voidwaker, with 100% energy saved for the desperation phase |
An amulet of blood fury is described as useful for learners but not to be relied on, because her off-prayer hits land hard enough that healing cannot be your plan.
Inventory and Supplies
One item is specific to this fight and is easy to forget: Sanfew serum, for the parasites.
- Sanfew serums or Relicym's balm. Drinking one before parasites burst weakens them, and you can click the Hitpoints orb to do it
- Saradomin brews and super restores
- Super combat potions and a magic damage boost if your setup uses one
- Karambwans for one-tick combo eating
- Your best special attack weapon (crimson kisten, voidwaker, burning claws or dragon claws) with 100% energy at the start of the desperation phase, plus a surge potion if you spec during the earlier phases
- A crush weapon for husks and weakened parasites, which you always max hit
- Darts or a fast option is not needed here, unlike Araxxor, because the spawns are melee'd
It is an instance with a deathbank. On death you respawn by the Pool of Nightmares and pay Sister Senga 60,000 to reclaim, and any unsafe death deletes the deathbank contents.
Mechanics You Have to Respect
The health structure is what makes this fight fast: three phases of 400 shield durability plus a final phase of 150 health, with three sets of totems, twelve in total, at 200 charge each. That is 1,350 physical damage and 1,200 charge damage when maging, 2,550 in total, against 7,800 for the original Nightmare.
Each phase has three specials: one spawn (husks or parasites), one paired with Grasping Claws (corpse flowers or spores), and one miscellaneous (Curse or Surge). Phase 1 picks set A or B at random and then alternates.
| Mechanic | What it does | Correct response |
|---|---|---|
| Standard attacks | Melee, magic and ranged. Max hits 73, 80 and 80, with the dash around 85 | Praying correctly fully blocks them, unlike the original Nightmare which only reduces them. Your window is 3 ticks for ranged and magic, and 2 ticks for melee. |
| Sleepwalkers | Increase by one per phase, capping at four at the end of phase three. Each has 10 hitpoints and you always max hit them | The number that reach her sets her power blast strength. If none are killed the blast always kills you. |
| Spores | Slow your attack speed by 2 ticks, doubled if you are maging, and drain 6 prayer points per yawn | Spores always precede six consecutive claw attacks in this version, so treat a spore as a warning rather than just a debuff. |
| Husks | Spawn in pairs and freeze you until killed. Blue and skinny uses magic, green and bulky uses ranged | Crush weapons always max hit them. Have no overhead prayer active before they appear, then pray magic once they do. She and the magic husk attack on the same tick. |
| Parasites | Burst out after around 18 ticks for heavy damage, then heal her until killed | Drink a Sanfew serum or Relicym's balm beforehand to weaken them. Weakened parasites are always max hit by crush. |
| Corpse Flowers | Split the room into four quadrants | The white-flower quadrant is safe. A red-berry quadrant deals rapid damage that heals her for double, and your attacks heal her there too. |
| Grasping Claws | Portals dealing 50 to 65 damage | Far more clumped around you than in the normal fight, so movement matters more. |
| Curse | Shuffles your protection prayers one to the right for 5 attacks | Clicking Protect from Melee gives Magic, Magic gives Missiles, Missiles gives Melee. Learn the mapping rather than reading the icons mid-fight. |
| Phase 3 prayer deactivation | She turns off your protection prayer if it was already active before the attack animation, and uses melee more often | Prioritise Protect from Melee, or Ranged while cursed, and expect to re-click. |
| Phase 4, the desperation phase | 150 health. She endlessly uses Grasping Claws and summons sleepwalkers one at a time | Each sleepwalker that reaches her causes a blast for 15 damage. This is where your special attacks go, and the crimson kisten is the strongest option here. |
The Kill, Phase by Phase
The fight is four phases with a totem stage between them. Treat the totems as a damage-only exercise and the phases as a reaction exercise.
- 1
Drink from the Pool of Nightmares to start the instance.
If you have zero Nightmare kill count you will get a one-time warning. You can ignore it, since the kill requirement was removed in August 2022.
- 2
Break her 400 shield durability with your crush setup while reacting to her standard attacks.
Praying correctly fully blocks them, so the whole phase is about reading the animation inside a 2 to 3 tick window.
- 3
When the phase's spawn special comes, respond by type:
kill sleepwalkers before they reach her, weaken parasites with a Sanfew serum before they burst, and for husks drop your overhead prayer, wait for them to appear, then pray magic.
- 4
Switch to your magic setup for the totems.
They have no defensive stats, so accuracy is irrelevant and only damage counts. Four totems at 200 charge each, three times over.
- 5
Repeat for phases 2 and 3.
The sleepwalker count rises by one each phase, capping at four, and phase 1's special set alternates from whichever of A or B it started with.
- 6
In phase 3, expect prayer deactivation and more melee.
Prioritise Protect from Melee (or Protect from Missiles while cursed) and re-click after each attack animation rather than trusting the prayer stayed on.
- 7
Handle Corpse Flowers by moving to the white-flower quadrant.
Never fight from a red-berry quadrant: it damages you rapidly, heals her double, and your own attacks heal her.
- 8
When Curse lands, remember the shift is one to the right:
click Protect from Melee to get Magic, Magic to get Missiles, Missiles to get Melee.
- 9
Phase 4 is 150 health of endless Grasping Claws and single sleepwalkers.
Walk in with full health, boosted melee stats and 100% special energy, dump your specs into her, and kill each sleepwalker before it reaches her, since each one that lands costs 15.
Solo Versus Team
Phosani's Nightmare is solo only. That is the core design difference from The Nightmare, and it is why the sleepwalker count is fixed per phase rather than scaling to player count.
The practical consequence is that every mechanic is on you simultaneously: prayer switching, spawn management, quadrant positioning and totem damage. There is no role to hide in.
If you are learning, the original Nightmare in a team is a reasonable place to practise reading her attack animations, but be aware the reaction windows and punishment are both harsher here, and that praying correctly fully blocks rather than reduces.
Common Mistakes and What Actually Kills You
This is a fight where most deaths trace back to one of five specific mistakes rather than to general under-gearing.
- 1
Ignoring the sleepwalkers.
If none are killed, her power blast always kills you. This is not a damage race you can win by tanking.
- 2
Drinking Sanfew serum after the parasites burst.
It has to be before. Click the Hitpoints orb to drink without swapping your inventory around.
- 3
Praying an overhead before husks appear.
She and the magic husk attack on the same tick, so go in with no overhead and pray magic once they spawn.
- 4
Fighting from a red-berry quadrant during Corpse Flowers.
It damages you fast, heals her double, and your own hits heal her.
- 5
Reading prayer icons during Curse.
The shift is one to the right and it lasts 5 attacks. Learn the mapping in advance.
- 6
Assuming your prayer stayed on in phase 3.
She deactivates a protection prayer that was already active before the attack animation.
- 7
Bringing magic accuracy for the totems.
They have no defensive stats, so accuracy items do nothing. Bring max hit.
- 8
Relying on an amulet of blood fury.
Useful for a learner, but her off-prayer hits are heavy enough that healing cannot be the plan.
- 9
Leaving items in the deathbank.
An unsafe death deletes them. Reclaim from Sister Senga for 60,000 before your next attempt.
Drops Worth Knowing
Two unique tables can both roll on the same kill: the armour, mace and staff table at 1/140, and the orb table at roughly 1/533. That gives an effective chance of any unique of about 1/111.
| Drop | Why it matters |
|---|---|
| Inquisitor's great helm / hauberk / plateskirt | 1/700 each. The crush set this fight is built around |
| Nightmare staff | 69/35,000 |
| Inquisitor's mace | 31/35,000 |
| Eldritch orb / Harmonised orb / Volatile orb | 1/1,600 each, on the separate orb table |
| Slepey tablet | 1/25, and guaranteed on your 25th kill since 25 June 2025. It unlocks the Drakan's medallion teleport straight to Slepe |
| Parasitic egg | 1/200. Unlocks a cosmetic skin for the little nightmare |
| Little nightmare (pet) | 1/1,400 |
| Jar of dreams | 1/4,000 |
| Elite clue scroll | 1/35 |
Combat Achievements
Because the fight is solo and instanced, Combat Achievement attempts here are entirely on your own schedule. There is no team to coordinate and no task requirement to wait for, unlike Araxxor.
Most of the tasks reward playing the phases cleanly rather than adding extra restrictions, so they line up naturally with learning the fight properly. Read the list before your first several kills so you are not repeating attempts later.
The Slepey tablet being guaranteed at 25 kills means the trip gets meaningfully shorter well before you finish a Combat Achievement set, which is worth factoring into your plan.
Ironman Notes
Phosani's Nightmare is one of the more attractive solo grinds for an Ironman because the inquisitor's set, the mace and the orbs are all things you otherwise cannot obtain, and the effective unique rate of about 1/111 is reasonable for what is on the table.
The Slepey tablet at 1/25, guaranteed by kill 25, matters more on an Ironman than it might look: the Drakan's medallion teleport straight to Slepe removes most of the travel time from the grind.
Sanfew serums are a Herblore cost you will pay every trip, so factor them into your herb planning rather than treating them as an occasional purchase.
FAQ
Does Phosani's Nightmare have a Slayer requirement?
No. This is the most common misconception about the fight. There is no Slayer requirement at all. The only hard quest requirement is Priest in Peril, for Morytania access.
Where is Phosani's Nightmare and how do I start the fight?
In the Sisterhood Sanctuary, the dungeon under Slepe in Morytania. Use Drink-from on the Pool of Nightmares, on the raised area north of the group Nightmare's arena, and you are put in your own instance. Drakan's medallion to Slepe is the fastest way there once the Slepey tablet drops.
How many phases does Phosani's Nightmare have now?
Four. Three shield phases of 400 durability, each followed by four totems at 200 charge (100 if you use magic), then a 150-health desperation phase. The 25 June 2025 update removed the old first phase, which is why older guides describe one more.
Do I need to kill the normal Nightmare first?
No, not since 13 August 2022. Sister Senga will let you fight Phosani's without a Nightmare kill. The game shows a one-time warning if your kill count is zero, and you can ignore it.
Why does everyone say to bring crush?
Her defence bonuses are +40 against crush versus +180 slash and +120 stab. Crush weapons also always max hit husks and weakened parasites, which makes the spawn phases much faster.
Should I bring magic accuracy for the totems?
No. The totems have no defensive stats, so accuracy does nothing there. Bring items that raise your max hit and skip anything that only adds accuracy.
How does the Curse special work exactly?
It shifts your protection prayers one to the right for 5 attacks: clicking Protect from Melee gives Magic, Magic gives Missiles, and Missiles gives Melee. Memorise the mapping rather than trying to read icons mid-fight.
How much faster is Phosani's than the original Nightmare?
Roughly three times faster. The total damage needed is around 2,550 when maging the totems, against 7,800 for the original, but the reaction windows are tighter and unblocked hits hurt much more.

Bottom Line
Phosani's Nightmare is gated by reaction speed and preparation, not by Slayer level or a prior Nightmare kill. If someone told you otherwise, they were describing the fight as it was before August 2022.
Bring crush for her and for the spawns, bring magic damage rather than magic accuracy for the totems, drink Sanfew serum before parasites burst, and always kill the sleepwalkers. Those four things account for most of the difference between a learner and a consistent kill.
If you want the inquisitor's set without learning a 2-tick reaction fight, our Phosani's Nightmare service does the kills on your account by hand.
