Enshrouded 1.0 opens two more Hollow Halls in Embervale. One is in the frozen Albaneve Summits and the other is in the flooded Veilwater Basin. Both are sealed crypts packed with Hollow enemies, and both stay locked until you bring the right Bone Key. The Collector crafts each key, and the Collector also gives you the quest that leads to each door. The two halls are chained together, because the Veilwater key needs a material that only drops inside Albaneve.
Quick answer: Have the Collector make a Bone Key for every hall, then use its corresponding quest to reach the entrance. Tackle Albaneve Summits before Veilwater Basin: the latter’s key requires Icy Giant Bones found inside the former.
Collector requirements for the new Hollow Halls
Everything runs through the Collector, Alden Crowley. You free him at the end of the Springlands Hollow Halls, and he is the same survivor who already makes the Revelwood, Nomad Highlands, and Kindlewastes Bone Keys. His list now runs to 81 recipes, including both new keys, Ectoplasm food, crypt furniture, Bone Arrows, and Eternal spells and arrows such as Eternal Hollow Wretch and Eternal Giant Bone Arrow.
He won’t craft much until he has a home. The Collector Needs Shelter quest asks you to build him a bed in a protected spot inside your base. A new bed goes to the nearest free survivor automatically, and you can hand it to someone else by aiming the Summoning Staff at it. The quest pops back up if the Collector ever loses his shelter, which is a quick way to spot why a recipe suddenly isn’t available.
Albaneve Summits and Veilwater Basin Bone Key recipes
Both keys are Rare items crafted at the Collector. Each recipe shows up in his menu once you pick up a specific tier of Ectoplasm for the first time.
| Bone Key | Item level | Ingredients | Recipe unlocks on |
|---|---|---|---|
 Albaneve Summits Bone Key | 33 | 1 Giant Bones, 1 Silver Bars, 20 Ectoplasm Gem | Picking up Ectoplasm Crystal |
 Veilwater Basin Bone Key | 43 | 1 Gold Bars, 1 Icy Giant Bones, 25 Ectoplasm Gem | Picking up Ectoplasm Cluster |
Each key opens the doors inside its own hall, not just the front gate, so keep it on you for the whole run. Some chests inside also cost Ectoplasm to open. Since 1.0, the chests in each hall’s final rooms take 25% less Ectoplasm than before, but it still pays to carry a reserve.
Where to get each Bone Key material
Together the two keys eat 45 Ectoplasm Gems, which is the slowest part of the whole process. Start making them early.
| Material | Source | Needed for |
|---|---|---|
 Ectoplasm Gem | Crafted at the Collector | Both keys |
 Giant Bones | Hollow Cyclops (first in Revelwood Hollow Halls) | Albaneve key |
 Silver Bars | Blast Furnace | Albaneve key |
 Gold Bars | Blast Furnace | Veilwater key |
 Icy Giant Bones | Enemies in Albaneve Summits Hollow Halls | Veilwater key |
Ectoplasm Gem
The Collector presses Bonemeal, Water, and Ectoplasm into gems, one gem per craft. Any Ectoplasm tier works, from Fragment through Shard, Crystal, Cluster, and Aggregate. The recipe unlocks when you first pick up an Ectoplasm Fragment, and it only works while the Collector is sheltered under a roof. Gems stack to 250.
Giant Bones
Giant Bones drop from the Hollow Cyclops. You first meet one at the end of the Revelwood Hollow Halls. If you already ran the older halls, there’s a decent chance a few are sitting in storage.
Silver Bars and Gold Bars
Both bars come out of the Blast Furnace. Silver Bars are smelted from Silver Ore and Coal, and the recipe unlocks the first time you pick up Silver Ore. Gold Bars are smelted from Coal and either Gold Ore or Archaic Shards.
Icy Giant Bones
Icy Giant Bones only drop from enemies inside the Albaneve Summits Hollow Halls, and the Hollow Wispwyvern in Veilwater drops them too. That first source is what locks the order. You need just one for the Veilwater key, but grab extras because other Collector recipes use them as well.
How to unlock the Albaneve Summits Hollow Halls
The Collector gives you a quest called The Albaneve Summits Hollow Halls, and it has three stages.
The hall is spider country. Expect Summit Spiders, Summit Spitting Spiders, Summit Bats, and the Summit Spider Mama. It’s also big and vertical, with 14 Grappling Points and 13 Updrafts to get around.
Don’t leave Albaneve without at least one Icy Giant Bones in your bag, or you’ll be running the hall again before you can craft the Veilwater key.
How to unlock the Veilwater Basin Hollow Halls
The Veilwater Basin hall comes from the Collector’s quest The Veilwater Basin Hollow Halls, which also has three stages.
Keen Games recommends bringing your snorkel here, a clue to how much of the area is underwater. The boss is Hollow Wispwyvern, which drops Ectoplasm Aggregate, Icy Giant Bones, the Hollow Wispwyvern Head, and Legendary Runes. The hall contains a puzzle and 3 Jump Pads as well. In the final stage, the objective marker appears in rooms with orange-glowing floor tiles.
Hollow Halls completion rewards and loot
You know a hall is done when its Master objective clears and the quest reward lands. Each hall pays XP plus a Rough Wood Block, and both are stuffed with chests.
| Reward or feature | Albaneve Summits | Veilwater Basin |
|---|---|---|
| Completion reward | 350 XP, Rough Wood Block | 400 XP, Rough Wood Block |
| Unique loot | 3 | 4 |
| Gold Chests | 7 | 6 |
| Silver Chests | 7 | 7 |
| Wooden Chests | 51 | 35 |
| Return Beacons | 5 | 5 |
| Grappling Points | 14 | 14 |
Two side quests hook into the new halls as well. Hidden Crafting Recipes — Hollow Halls (recommended level 25, 75 XP) starts when you find a hidden recipe inside any hall and asks you to collect every one across each biome’s Halls for decorative pieces. Red Marble Decoration (recommended level 32) starts from a note inside the Veilwater Basin hall. Push through to the end of that hall to find the red marble arch recipe, which rewards the Small Red Marble Arc and the Red Marble Column.
