Plane of Nightmare
Plane of Nightmare Guide
Plane of Nightmare is the step after Crypt of Decay. This zone is built around Thelin Poxbourne, the hedge maze, Nightmare essence farming, the Black Bastardsword hand-in, Terris Thule, and the next Chapter 1 mirror upgrade.
Progression Overview
- Kill valid trash to gather Nightmare essence.
- At 1,000 essence, a hostile PoN Essence Chest spawns at the credited player and the essence count resets.
- Speak with Thelin Poxbourne and enter the hedge maze when ready.
- Inside the hedge path, collect the five cursed token drops and combine them in a Tier Upgrade Kit to make Black Bastardsword.
- Hand Black Bastardsword to Thelin to summon a construct of nightmares.
- Kill the construct, loot Dagger Blade Shard, and hand it to Thelin to receive Thelin's Dagger and advance the Terris story step.
- Build Eclipsed Midnight Mirror of Nightmares before leaving this tier if you are following reflected rewards.
Nightmare Essence Count
Most normal trash in Plane of Nightmare counts toward the essence system. Bosses, pets, helpers, excluded event NPCs, and several special-script NPCs do not count.
- 1 valid trash kill = 1 Nightmare essence.
- The counter is stored per character.
- Credit can be found through the player, pet, bot, bot pet, group, or raid ownership where possible.
- Same-IP group or raid members can receive shared essence credit.
- At 1,000 / 1,000, the script spawns a hostile essence chest at the player and resets the counter.
Essence Chest Loot
The essence chest is not a passive container. It appears and attacks.
| Item | Chance / Notes |
|---|---|
| Elemental Essence | 100% |
| Twilight Reliquary | 100% |
| Fumes of Force | High chance from the fumes pool |
| Fumes of Tranquility | High chance from the fumes pool |
| Fumes of Knowledge | High chance from the fumes pool |
| Fumes of Endure | High chance from the fumes pool |
| Fumes of Spread | High chance from the fumes pool |
| Jewel of Nightmares | 50% |
| Gob Gobby Night Terror | 25% |
| Skelly Bonez Night Terror | 25% |
The Hedge Maze
The maze starts from Thelin Poxbourne when you tell him you are ready. The script moves players to the hedge start while preserving the current instance.
Once the maze begins, it is intentionally nasty:
- A random Thelin curse is applied: Thelin's Disarm, Thelin's Voice, Thelin's Pace, or Thelin's Fortitude.
- After roughly two minutes, the hedge starts draining HP and mana from players and bots.
- Coven wolves begin spawning during the event.
- The maze can periodically move players back to the start.
- Thelin's silence and presence effects can hit players and bots.
- After the lava warning, players without Spirit of Eagle can take heavy lava ticks.
Treat the hedge as its own event, not just a hallway. Bring movement, recovery, and patience.
Hedge Token Combine: Black Bastardsword
Thelin explains that five cursed creatures are tied to five token pieces. Each token has a strong drop chance from its matching named.
| Named | Token | Chance |
|---|---|---|
| The Scourge Hobgoblin | Shard of the Hobgoblin | 75% |
| The Gnarled Treant | Splintered Treant Branch | 75% |
| The Dark Visage | Veil of the Visage | 75% |
| The Nightstalker | Nightstalker Fang | 75% |
| The Coven Wolf | Coven Wolf Paw | 75% |
Combine all five tokens in a Tier Upgrade Kit to create Black Bastardsword.
Hand Black Bastardsword to Thelin to summon a construct of nightmares.
Construct And Thelin Hand-Ins
A construct of nightmares is the Thelin-spawned boss after the Black Bastardsword hand-in.
Notable construct loot includes:
| Item | Chance / Notes |
|---|---|
| Dagger Blade Shard | 100% |
| Elemental Essence | 100% |
| Twilight Reliquary | 100% |
| Core of the Construct | 75% |
| Thelin's Mask of Nightmare | 25% |
| Gob Gobby Night Terror | 25% |
| Skelly Bonez Night Terror | 25% |
| Face of Darkness, Face of Elixer, Face of the Guardian, Face of the Crazed | Shared face pool |
| Thule Shoulders of Casting, Thule Shoulders of Healing, Thule Shoulders of Combat, Thule Shoulders of Fortitude | Shared shoulder pool |
After the construct dies, hand Dagger Blade Shard to Thelin. He returns Thelin's Dagger and triggers the Terris story step.
Lair of Terris Thule / PoNb Access
Thelin's Dagger is part of the Plane of Nightmare story flow, but it is not the final access instruction for Plane of Nightmare B. PoNb access comes from a twelve-piece Nightmare collection chain that ends with a right-click key.
First, collect the six outer Plane of Nightmare relics and combine them in a Tier Upgrade Kit to create Totem of the Dreamless:
| Outer Relic | Source / Note |
|---|---|
| Wailing Pendant of the Sister | The Wailing Sister |
| Matriarch's Shattered Fang | Terror Matriarch path |
| Tyrant's Iron Visage | Outer Nightmare named path |
| Twisted Spindle of Deyid | Deyid the Twisted |
| Anguish Lord's Shackles | Hobgoblin Anguish Lord chain |
| Mujaki's Mocking Lantern | Mujaki path |
Then collect the six Maze of Nightmares relics and combine them in a Tier Upgrade Kit to create Totem of the Restless:
| Maze Relic | Source / Note |
|---|---|
| Scourged Charm of Poxborne | Maze / Poxborne path |
| Gnarled Heart of the Treant | Gnarled Treant path |
| Visage of the Dark One | Dark One / visage path |
| Nightstalker's Hollow Fang | Nightstalker path |
| Wolf's Blood Sigil | Coven wolf path |
| Core of the Construct | A construct of nightmares |
Finally, combine Totem of the Dreamless and Totem of the Restless in a Tier Upgrade Kit to create Key of the Shadowed Lair.
Important: right-click Key of the Shadowed Lair to unlock access to the Lair of Terris Thule / Plane of Nightmare B. Once access is unlocked, you can enter the public version or request an instance.
Nightmare Mirror Upgrade
The Nightmare mirror recipe uses the Tier Upgrade Kit. The required pieces are:
| Component | Source / Note |
|---|---|
| Decaying Mirror of Eclipsed Midnight | Carried forward from the prior mirror line; this is the base mirror component, not a Plane of Nightmare essence chest drop. |
| Crown of Nightmares | Drops from Terris Thule. |
| Jewel of Nightmares | Drops from the PoN essence chest. |
Combine those pieces in the Tier Upgrade Kit to create Eclipsed Midnight Mirror of Nightmares.

Practical Reminders
- The hedge maze is the core mechanic of the zone and deserves preparation.
- Essence credit is for valid trash kills, not every NPC in the zone.
- The essence chest is a fight and a reward source.
- Keep Jewel of Nightmares and Crown of Nightmares if you are upgrading the mirror.
- Keep the five hedge tokens until you can combine Black Bastardsword.
- If a hand-in fails, confirm you are using the correct Thelin version and the exact item.
