Revelwood Hollow Halls
The Revelwood Hollow Halls is the group-content dungeon beneath Revelwood. Push through its Barrier Doors and Reanimator swarms to the Hollow Cyclops at the end, and it pays out in Ectoplasm, exclusive gear, and collectible artifacts.
How to unlock the Revelwood Hollow Halls
Start quest: Ectoplasm Press For The Collector (from the Collector).
Key required: Revelwood Bone Key
Before you go in
- Craft or loot the Revelwood Bone Key — the vault door won't open without it.
- Hit at least the top of the Revelwood band (Lv 10 - 15) so the Hollow Cyclops finale is survivable.
- Slot poison resistance — Toxic Slime chips your health across the whole dungeon.
- Bring AoE or fast single-target for Reanimator bone-piles; they spawn endless Hollow until smashed.
- Hollow-family weapons roll Sacred Enhancement (+10% vs Hollow) — carry one if you have it.
- Pack healing food + a repair kit; there's no workbench once the Barrier Doors seal behind you.

Walkthrough & mechanics
Every Hollow Halls run reads the same four beats — clear the room to drop the Barrier Doors, kill Reanimators on sight, mind the Toxic Slime, and save resources for the Cyclops.
Barrier Doors
Runed doors stay sealed until you clear the room's enemies or track down the hidden runes that power them. No shortcut — the dungeon gates your progress on combat.
Reanimators
Bone piles that spawn an endless stream of Hollow until you destroy the pile itself. Prioritise them or you'll be swarmed while the real fight stalls.
Toxic Slime
Green poison coats floors and walls, chipping your health while you stand in it. It can be mined with a pickaxe for crafting — but clear a safe path first.
Hollow Cyclops
One or more one-eyed giants guard the final chamber — the gear-check that ends every run. Bring the resistances your build is weakest against.
