Sker Ritual House of the Damned
Escape the farmhouse, restore gas and power, harvest hearts with the Corpse Grinder, and banish Canwyll Corph.
House of the Damned is Sker Ritual’s first post-1.0 episode, released July 2024 on PC, PlayStation, and Xbox. Wales Interactive traps your squad inside a cursed farmhouse with no power, no outdoor access until mid-quest, and a Pale Dog wave every fifth round. Unlike the four launch maps, House does not count toward the God Killer permanent unlock—that chain requires Hardcore hidden objectives on Lavernock, Ashes, Sewers, and Fortress only. House still offers its own Hardcore secret, music Easter egg, map achievements, and the map-exclusive Corpse Grinder wonder weapon. Clear the launch walkthroughs first, then use this guide as your objective order from spawn to Canwyll Corph.
Escape the House
You begin in the basement dungeon after interacting with the jukebox, which starts music and a dog wave. Two Abominations spawn and the exits seal until you prove there is no easy way out. Open the upstairs door for 500 points, confirm the route is blocked, and the next mission chain unlocks. This intro teaches House’s tight corridors: backpedaling is dangerous, so always know your fallback room with a single entrance. Track early objectives in the objective checklist because House runs three parallel quest lines later.
Powerless: gas levers and pressure
House starts without electricity or perks. The Powerless chain has two halves: gas and power.
Restore gas flow: Interact with the kitchen pipe near the exterior door, then kill five Hags inside the marked circle. That opens the X marks the spot step—white crosses on first- and second-floor walls. Melee or shoot the crosses to expose gas pipes; only some contain levers. Pull all five gas levers spread across both floors (not every X has a lever).
Equalize gas pressure: Read the total on the basement pressure console, then find numbered valves whose values add up to that total. Known valve examples include 35 in the first-floor kitchen, 42 in the second-floor bathroom, and 73 beside the main basement meter—your target sum rotates each run.
Restore electricity: In the basement, interact with the large red lever to reveal a three-digit sequence. Find numbered switches in fixed rooms (lounge with the Hanging Man, first-floor living room stair base, second-floor master bedroom, music room near the jukebox, basement near Swift Death, first-floor hallway outside the Hanging Man’s room). Flip them in order, then hold the power switch area to energize the house. Perks and Pack-a-Punch finally unlock.
Furnace and outdoor access
Restricted Access sends you to the sub-basement mannequin room—one of the scariest spaces on the map. Press the red wall button to cycle purple lights on mannequins; memorize the symbol code near the lit figure (codes rotate per run but stay stable until you re-press the button). Enter those symbols on the basement furnace door.
Fuel the furnace with five entrails dropped from zombie kills, then deposit them. Power fully restores, the exterior opens, and you can reach the ritual site on the house grounds. Read the stone there to begin the three material quests below.
Book of the Dead and Mother’s Head seals
Open the graveyard mausoleum and pick up the Mother’s Head lantern—it occupies a weapon slot and reveals hidden symbols like a torch. Thomas spawns when you grab it. In the basement tunnel near Get Up N Go, equip the Head to see a blue secret door; interact to start the ghost passage.
Only in death will you find the way: You must get downed and enter ghost mode. While ghosting, the wall opens into a hidden chamber with the Book of the Dead. Interact to revive for free without losing your self-revive token—but this fails if no self-revive exists anywhere on the team and the down would end the run.
Equip the Mother’s Head again and destroy three seals visible only with the lantern out: basement left of the furnace, first-floor living room beside the stairs, and second-floor closet opposite Elixir of Life. Collect the Book of the Dead and place it at the ritual site.
Heart of the Sons: Corpse Grinder and marked corpses
Take the wooden cross from the garden well and place it in the coffin near the tomb. Urns spawn around the exterior—listen for audio cues. Known urn spots include a tree near Fast Hands, the front porch, and back porch; the destructible urn rotates each run but always glows when active. Destroy all urns, collect explosives from the coffin, and detonate the sealed well.
Drop into the well chamber to find the Corpse Grinder embedded in the Mother’s corpse. Pale Hounds spawn—budget points for the weapon and exit door. Shoot the three marked corpses around the house with the Grinder, interact with their chests to harvest hearts, and deposit all three at the ritual site. Corpse locations shuffle but stay marked.
Defeat the trio: Abraham, Isaac, and The Stranger
Interact with the family photo above the living room fireplace to spawn Abraham, Isaac, and The Stranger together. Defeat all three and collect portrait pieces, reassemble the Pryce family photo, then get kills in the fireplace radius to charge it. Place the finished portrait at the ritual site. This is the heaviest add fight before the boss—consider doing it earlier if you need points or want the Grinder first.
Walk with Ghosts and Canwyll Corph
Once Book, hearts, and portrait sit at the ritual site, equip the Mother’s Head and escort The Father’s ghost. Only the Head holder sees him, but he follows any nearby player. He stops at four blood-spill points: mausoleum, Hanging Man, second-floor Mutilated Pig, and mannequin room—stand in each radius and get kills before he moves on. Escort him back to the ritual site to start the Canwyll Corph boss fight.
Canwyll Corph is House’s main boss. Use Pack-a-Punched primaries, AoE miracles from miracle builds, and the Corpse Grinder for close bursts. Downing him completes the main quest and spawns a green portal at the burial ground for the hidden objective.
Hardcore hidden objective and music EE
After main quest completion, interact with the green portal. Hunt the demon lamb (common spawns: tomb roof, master bedroom, Grinder room, mannequin room). Shoot the second-floor Mutilated Pig with the Corpse Grinder, then quickly interact with basement pig heads on sticks—repeat with the outdoor pig head near the difficulty sword. Listen to animal sound counts from the pig, dog (graveyard), and goat (basement), then enter those numbers under the corresponding masks in the mausoleum.
Re-equip the Mother’s Head and collect hidden cache items: tree stump between tomb and house, loose floorboard between kitchen stairs and basement, brick on the backside of basement stairs. Insert the Lamb’s Seal into the basement lamb head altar and feed it souls with nearby kills. Free the lamb from the sub-basement Lamb Box (right of mannequin room stairs) and escort it to the ritual site for a second Canwyll Corph fight. The separate music Easter egg uses voice lines near unlit treble clefs across the house—see easter eggs hub for full song steps.
House Hardcore awards cosmetics and prestige but does not add a God Killer seal. See Hardcore overview for launch-map requirements vs episode secrets.
Dolls and collectibles
House hides collectible dolls indoors and outdoors across basement, living room, porch, fields, and graveyard sectors. Doll hunting ties to achievements and the broader collectible checklist on collectibles guide. Route doll pickups during gas and power steps to avoid redundant backtracking.

Complete the well cross and urn quest, blow up the well, buy the Grinder from the Mother's corpse chamber, then shoot three marked corpses and deposit their hearts at the ritual site.

It reveals hidden seals for the Book of the Dead quest, opens the ghost-only secret tunnel, and lets you see The Father during Walk with Ghosts escort steps.

Abraham, Isaac, and The Stranger spawn from the fireplace family photo. Defeat all three, rebuild the portrait, spill blood at the fireplace, and place it at the ritual site.
