Every step in order, no explanations. Open the full manual when a step needs detail.
Override the four Corruption Engines
! Four in total. Watch the map diagram — a green light appears for each one you finish, so that is your tracker rather than memorising locations.
Learn the portals and jump pads
! Worth walking once early to learn the connections. Stamin-Up and constant sliding make it much quicker.
Trap the Apothicon
! Timing is everything — fire early and you just watch it swim past. Wait for it to be genuinely in front of the trap.
Free Pack-a-Punch
! Sources differ slightly on whether it is one large orb or three yellow sacs — shoot every yellow thing at the far end and you will be right either way.
Get comfortable inside the Apothicon
Shoot the four gravestones
! That spells Richtofen, Dempsey, Takeo, Nikolai — the order their souls went into the key. The graves glow red with an audio cue. Doable from round 1, so get it out of the way early.
What you need first
! Completable solo. The Gateworms from the previous four maps are not needed here — only for the super Easter egg.
Shoot the gravestones
Reel 1 — the Keeper ritual
! Zombies swarm the Keeper the moment it starts. Protect it for around two minutes until it vanishes and drops the reel. Play this one on the audio player upstairs in Nacht.
Reel 2 — nine Arnies
! After all three land, kill the three Margwas that spawn. Repeat twice more for nine holes total. Max Ammos make this far less painful solo. The reel appears on the middle bridge above the acid pool, and plays in Kino.
Collect the body parts
! The walkthrough I built from lists these six; two other guides describe seven, with the extra one at Mob of the Dead. If six does not complete the step, sweep Mob of the Dead and tell me so I can fix this.
Reel 3 and meet Sophia
Reflect the turret beams
! Done correctly, the beam visibly bounces off toward Sophia and you are kicked off the turret immediately — that is your confirmation. After all four, Sophia becomes solid.
Fetch the Kronorium
Find an Apothicon Egg
Hatch the Gateworm
Dig up a Rune of Creation
! Repeat the egg, hatch and rune cycle four times — one for each of fire, ice, wind and electric. This is the longest stretch of the quest by a wide margin.
Boss room — Simon Says
Boss room — four phases
! Clearing all four drops the Summoning Key out of the sky.
Throw the key at seven targets
Shadow Man boss fight
! Repeat the charge-and-throw cycle until the Shadow Man ends up inside the Apothicon’s mouth. Then interact with the book to finish it.
