Treat each five-floor portal as a chance to bank the run
Hollow Crypts is Akneo’s browser tactical RPG. The launch description says extraction portals open every five floors. Leaving at a checkpoint banks Gold and XP; continuing toward the final boss risks a wipe and an empty-handed return. This guide concerns that game, not Skyrim’s Dimhollow Crypt.
The practical choice is between securing the current run and exposing those unbanked rewards to another stretch of combat. Before continuing, inspect your party’s condition and resource pools. If your immediate aim is to bring back progression, using an available extraction portal follows the game’s stated cash-out mechanic.
There is no verified health percentage, mana threshold or mathematically optimal extraction floor in this guide. We have not completed a dungeon run. The official description supports the risk trade-off, but not a promise that a particular team can safely reach the boss.
Know the four launch characters before judging a team
The developer presents four core operatives with distinct jobs. The table summarizes their published kits; it is not a tier list, damage comparison or claim that every listed ability is available immediately.
| Operative | Role | Published strengths |
|---|---|---|
| Retired Knight | Tank | Aggro control, party overshields and intercepting fatal blows intended for allies |
| Hena | Dark Swordmaster | Surviving at 1 HP and abyssal area attacks |
| Dex | Battle Mage | Earth magic, resource recharge, firestorms and emergency squad revival |
| Shira | Trickster | Status immunity, dodge stances, burn damage and reduced squad mana costs |
Read ranks as unlock stages, not keyboard shortcuts
Skills, stances and ultimates unlock across ranks F, D, C and B. Those letters describe progression ranks in the launch notes. They are not documented combat hotkeys. Check the skills currently unlocked on a character before relying on a later part of their kit.
For example, Dex’s listed squad revival is a reason to inspect that character’s available abilities, not proof that every starting Dex can revive the team immediately. The same distinction applies to the Knight’s sacrifice, Hena’s survival effect and Shira’s resource support. The official page does not give a full skill-by-rank chart or exact cooldowns.
Use roles to identify a missing capability in the party: protection, damage or resource support. That is a way to read the published kits while choosing a team. It does not establish a strongest composition, a fixed rotation or an ability order tested by Nisu.
Check the dungeon gate as well as the floor count
The launch build lists Forgotten Cellar as an F-rank dungeon with ten floors, including slimes, scavengers and the Cellar Troll. Sunken Catacombs is the longer D-rank expedition, with fifteen floors, crypt wardens and gargoyles.
Sunken Catacombs is gated by the party’s average rank. The important word is average: do not treat one promoted character as proof that the whole party meets the requirement. Consult the entry requirement shown in your game. The listing does not provide the exact numerical average or a tested fastest promotion route.
Because extraction opportunities are described at five-floor intervals, the longer expedition asks you to keep making the bank-or-continue decision. Its higher-tier rewards do not remove the wipe risk. Match your next attempt to the progression you want to secure, rather than assuming the deepest accessible dungeon is always the best choice.
Keep the browser that holds your guild progress
Akneo says local storage keeps guild treasury, hero levels and unlocked rosters. That describes browser-local saving; the page does not document a shared cloud account or automatic transfer to another device.
Return to the same browser and site when checking existing progress. Clearing that site’s storage can remove local data. This guide has not tested a save export, recovery process or cross-device transfer, so it does not promise those features.
A wipe is described as losing the run’s unbanked rewards, while treasury, levels and rosters are the persistent data named in the local-save description. Do not turn “empty-handed” into an unsupported claim that a wipe deletes the entire guild or browser save.
Quick help
How often can I extract?
The launch description says extraction portals unlock every five floors. Use a checkpoint to bank the run’s Gold and XP instead of risking another stretch.
Does wiping erase my whole guild?
The official description says a wipe leaves you empty-handed for the run. It separately names treasury, levels and unlocked rosters as locally saved progress; it does not say a wipe deletes the whole save.
Why can’t my party enter Sunken Catacombs?
The D-rank expedition is gated by party average rank. Check the current entry requirement and the whole party, not only your highest-ranked hero.
Are F, D, C and B combat keys?
They are progression ranks in the official ability-unlock description. This guide does not present them as keyboard controls.
Which team is strongest?
No comparative team test is available here. Use the published roles to understand protection, damage and resource support, then check the abilities your characters have actually unlocked.
