The Sanctuary is the main building in Last Asylum Plague. It is already standing when you start, at level 1, and the rest of the town waits on it. The plot is 4×4. You cannot move it, and you cannot demolish it. It levels to 30.
Each level raises the building’s Might, and it raises four hero numbers shown on the building panel: Hero Level Cap, Hero HP, Hero ATK, and Hero DEF. Attack and defense from the Sanctuary are the same value at every level. The hero level cap stays at 5 through Sanctuary Lv.3. It jumps to 15 at Lv.4 and 25 at Lv.5, then climbs by 5 each level. At Lv.30 the cap is 150, and the building’s Might is 384,300.
The in-game line for the building is short: “The sturdiest sanctuary that heals the afflicted and repels dark creatures.” What it actually does is gate the town. New buildings, a lot of buttons on the main screen, and every later upgrade on your other buildings all check this level.
Upgrading
You start at level 1, so the first upgrade you pay for is the one to level 2. From level 3 on, the upgrade also asks for Stars. That is the star total from the town clinic, and the check is only that you already have at least that many. The upgrade does not spend them. Level 3 asks for 17. Level 10 asks for 112. From level 28 on the requirement sits at 326 and does not climb any further.
The other requirements are buildings. From Sanctuary 12 through 30, the Research Lab has to be one level behind the level you are raising. Sanctuary 12 needs Research Lab 11, and Sanctuary 30 needs Research Lab 29. Sanctuary 11 is the odd one: it only needs Research Lab 7. Alongside the lab, the second and third building rotate. Walls, Training Grounds, Alliance Hall, the Infirmary, the faction statues, Barracks, and the resource buildings each take a turn. The exact list is in the table.
Grain, Timber, and Herb in the table are the base cost, before any build-speed bonus. Farms produce the Grain, Lumberyards produce the Timber, and Herb Gardens produce the Herb. Herb is not on the bill until level 9. Build speed from research, survivors, and the like shortens the timer you see, and the game prints the original time beside it once those bonuses are active. Alliance Help then cuts time off a timer that is already running.
The diamond button is not a fixed price, which is why this table does not have a diamond column. The game prices the seconds still left on the clock as 0.125 times those seconds, raised to the power 0.8925, then rounds up. If you are short on Grain, Timber, or Herb, it adds 1 diamond for every 1,000 you still need, also rounded up. Stars are not part of that bill. The Builder’s Hut adds free speedup that is taken off before that diamond price is worked out. The hut gives none at level 1, 10 seconds at level 2, and 30 minutes at level 30. That is why a very short upgrade can show as Free even though the printed build time is still a couple of seconds. The free time is not removed from the timer on the upgrade button itself.
When the upgrade finishes, the level-up screen pays the reward in the last column and lists any building type whose first level requires the Sanctuary level you just reached. Most of the reward is Antitoxin. From level 7 through 17 you also get an 8 hour Shield, a Direct Relocate, or an Alliance Relocate on some of the levels.

Buildings that open
The level-up screen lists a building when its level 1 requirement is that Sanctuary level. Curios and event decorations (the amulets, the nutcrackers, and similar pieces) are on the level 1 list, which you already meet at the start. The buildings that matter are below. A few of them also want something else, and that extra requirement is noted.
- Level 1, already met: Farm, Lumberyard, and Herb Garden.
- Level 3: Builder’s Hut.
- Level 4: Walls, Tavern, Gear Workshop, Explorer’s Camp, and Squad 4. Squad 1 is slightly different. Its first level asks for Explorer’s Camp Lv.1, and Sanctuary Lv.4 is what it asks for when you take Squad 1 to level 2.
- Level 5: Antitoxin Workshop, Smelting Workshop, Weaving Workshop, and Epigraph Workshop. Epigraph Workshop also stays locked until the server is 78 days old.
- Level 6: Falcon Tower, Barracks, Infirmary, Alliance Hall, Scout Squad, Nomad Trader, and Training Grounds. Alliance Hall also wants Falcon Tower Lv.1. Training Grounds also wants Barracks Lv.1.
- Level 7: Research Lab, Arena, Raven Nest, Warrior Statue, and Temple. Arena also wants Squad 1 Lv.1.
- Level 8: Squad 2, Watchtower, and Curio Hall.
- Level 9: Monument, Black Ops, and the 2nd Workbench. The workbench also wants a Research Lab.
- Level 10: Private Stable and Alliance Stable.
- Level 11: Warlock Statue.
- Level 12: Ranger Statue.
- Level 14: Lord Statue. This one also waits until Era 1 has started.
- Level 15: Hall of Honor and Raven Workshop.
- Level 20: Squad 3.
- Level 22: Soldier’s Rest. Like the Lord Statue, it waits until Era 1 has started.
Three storage buildings never show on that list, because they check a production building instead of the Sanctuary. Granary needs Farm Lv.2. Lumber Depot needs Lumberyard Lv.2. Herb Storage needs Herb Garden Lv.2. Later levels of those storages do start asking for a matching Sanctuary level.
Extra copies of Farms, Lumberyards, Herb Gardens, and the workshops are already placed in locked parts of town. An area opens when you clear its town chapter, not when the Sanctuary hits a number. You will often open a new plot around the same time you level the Sanctuary, but the two are separate.
After a building is placed, raising it further usually demands the same Sanctuary level as the level you want. A level 20 Training Grounds needs Sanctuary 20, and the same pattern shows up on the Research Lab, the walls, the statues, and most of the resource buildings. That is the slow part. The Sanctuary is not just the key to new construction. It is also the ceiling on everything you have already built.
What else waits on this level
A lot of buttons on the main screen are tied to the Sanctuary as well. These are the ones you will actually notice.
- Level 2 puts the diamond count on the resource bar.
- Level 3 opens the Dense Forest chapters, and it opens territory cosmetics: the castle skin, aura, nameplate, and chat bubble.
- Level 4 opens the main mission list, the gift shop, the bag, mail, the activity list, and the first recharge. The alliance button also wants Sanctuary 4, and it still needs an Alliance Hall before it will open.
- Level 5 opens daily missions, the Age screen, and online rewards.
- Level 6 opens the VIP popup.
- Level 8 opens the leaderboards.
- Level 10 opens Escort, once the server reaches day 3. The alliance train opens at the same Sanctuary level, once the server reaches day 14.
- Level 15 opens Raven gear, and you also need the Raven Nest built.
War Frenzy and shields
A Shield keeps your territory safe from scouting and attacks. It does not cover troops that are already outside. Starting a military action drops a Shield you already have. Those actions are scout, reinforce, garrison, attack, and rally, used on a territory, a camp, a resource tile, or a city.
Those same actions also start War Frenzy. The description says it kicks in at Sanctuary Lv.9, adds 5% Troop ATK, and blocks Shields until it runs out. It also says the timer gets longer as the Sanctuary levels up. Currently that timer is 15 minutes at every level from 1 to 30. If you are shielded, the game asks you to confirm, because the action will drop the Shield and start the 15 minute timer.
Survivors
The Sanctuary has two survivor posts. The two survivors assigned to it are Freya, the Bounty Hunter, and Elaine, the Shadow Mercenary. Freya brings extra treasures back from Falcon quests. Elaine raises every hero’s command and adds a large attack bonus. Neither of them is in the normal survivor recruit pool. They come from the VIP offers, and the random UR survivor chest calls out that it excludes both of them.
Notes
- One Sanctuary. It starts at level 1 on a fixed 4×4 plot, and the max level is 30.
- Might goes from 900 at level 1 to 384,300 at level 30. The hero level cap goes from 5 to 150.
- Stars are a threshold, not a material. Grain, Timber, and Herb are the materials, and Herb starts at level 9.
- From Sanctuary 12 up, keep the Research Lab one level behind or the next Sanctuary upgrade will not start.
- The time in the table is the base time. Build speed, Alliance Help, and the Builder’s Hut free speedup all change what you pay in minutes and in diamonds.
