Last Asylum Upgrade Guide

Published: 2026-10-25

Upgrade the Sanctuary first, then the Research Lab and Development research, then Training Grounds, your main heroes and their gear. The Sanctuary caps every other building and every hero level, so it sets the pace for the whole account. This guide gives the order, the milestones by Sanctuary level and the fastest ways to raise might.

What to Upgrade First

Several progression guides give the same core order, and the building tables agree: buildings are capped by the Sanctuary, hero levels are capped by the Sanctuary, and the Sanctuary itself asks for the Research Lab more than any other building. Follow these stages in order and move down the list only when the stage above keeps your queues busy.

1. Sanctuary. Raise it whenever the resources are ready. Its level decides the hero level cap, which is 100 at level 20 and 150 at level 30. See the Sanctuary upgrade requirements for each step.
2. Research Lab and Development research. The lab is required by 20 of the 29 Sanctuary upgrades. Development and Economy nodes shorten later timers and raise output.
3. Training Grounds and troops. Their level sets your best soldier tier, and trained troops add a large share of your real strength.
4. Main heroes. Pick one squad and put levels, stars and skills there first. The best team section shows which heroes to build around.
5. Gear for the same heroes. Forge gear on your main squad before you spread it across the roster.
6. Raven, Epigraphs and the rest. They add permanent bonuses and come after the stages above.

Upgrade Requirements

Three rules explain most blocked upgrades. A building cannot pass the Sanctuary level. Many Sanctuary levels list other buildings at set levels, from the storage buildings at level 4 up to Research Lab 29 at level 30. Hero levels cannot pass the hero cap of your current Sanctuary. The building requirements section lists the chains that start a few buildings, such as Training Grounds needing Barracks level 1.

The table shows the checkpoints where the requirement list changes character. Level 4 asks only for the three storage buildings, level 7 brings in Training Grounds and the Alliance Hall, level 11 adds the Research Lab, and from level 12 to level 30 it asks for the lab one level below the target. Grain and Timber cost the same amount at each level, so one column covers both. Costs and times are base values before bonuses, and the Sanctuary page lists all 30 levels.

Upgrade Milestones

The table shows what each Sanctuary level opens: new buildings, extra copies of buildings you already have, and the soldier tier of a Training Grounds at the same level. The hero level cap is the cap of that Sanctuary level. Levels with no new unlock are left out.

Best Buildings to Upgrade

The best buildings to upgrade are the ones on the Sanctuary list. Across 29 upgrades, the Research Lab tops the list with 20 requests and Training Grounds follow with 9. Walls and Alliance Hall come next with 6 each, and Warrior Statue has 5. Farm, Lumberyard, Herb Garden and the three storages appear 3 times each, and Antitoxin Workshop 4 times. Builder's Hut is never required, but its free speedup time rises to 30 minutes at level 30, so it is worth keeping level with the Sanctuary.

The building priority list adds costs and might for each of them. For output rather than requirements, the Herb Garden comes first, and the resources page explains the order of Farm, Lumberyard and storage.

Research Priority

Research gives permanent bonuses to the whole account, and the order matters more than the total. Most guides agree on this route: Development first, then Economy, then Alliance Duel as soon as the lab reaches level 15. Development has 18 technologies and is the cheapest branch in the tree. Alliance Duel has 14 technologies and unlocks the reward chests that give Study Scrolls and hero shards. Hero, Soldier and Squad branches follow, and Elite Troop, which unlocks tier 10 soldiers, comes last among the major branches. The research guide has the full branch table and the Study Scroll rules. This video walks through research and upgrades step by step.

Hero Upgrade Order

One guide measures heroes at over 9 million power at high levels, more than any other source, but their level cap depends on the Sanctuary, so buildings come first. Spend hero materials on the five heroes in your main squad and ignore the rest until that squad is strong. Level damage dealers first, then tanks, then support heroes. Stars and skills also start with the damage dealer. The heroes page has the cost tables and the calculator for each step.

Gear Upgrade Order

The Gear Workshop opens at Sanctuary 4. Push it to level 10 early, before you invest seriously in gear, and then to level 20, where the game unlocks Gear Promote. Gear the main squad before the bench. Tanks need armor and boots first, and one guide puts weapon and gloves first for damage dealers. The gear guide covers blueprints, materials and slots.

Troops and Training Grounds

Train troops at the highest tier you have, and promote old low-tier troops into higher tiers rather than training new ones from scratch. The tier you can train depends on the Training Grounds level: tier 6 opens at level 17, then 20 gives tier 7, 24 gives tier 8 and 27 gives tier 9. Level 30 reaches tier 10, but you must also finish the Elite Troop research. A common week-one goal is Sanctuary 20, which opens tier 7. The troops page covers training and morale.

Fastest Way to Increase Might

Total might comes from five sources: buildings, research, heroes, troops and the Raven. One guide notes that buildings mostly inflate the visible score, while heroes and troops add the real strength. The might page explains each source, and this section shows where the next upgrade pays back most.

1. Raise many buildings through their cheap levels. A million resources spent on early levels buys about 3,111 might, the same million buys 213 in the middle levels and only 40 in the last ten. The first ten levels are about 78 times better value than the last ten.
2. Level the heroes in your main squad. Hero might is the easiest and cheapest way to raise your score once the Sanctuary cap allows it.
3. Train troops at the highest tier available, and promote low-tier troops instead of training new ones.
4. Finish Development research first, then combat research for your squads.
5. Level the Raven and equip its gear and Epigraphs once it unlocks. The Raven page has the details.

Daily Upgrade Routine

A short daily routine keeps every queue busy without spending speedups early. Most progression guides share the same core steps.

1. Finish the Chapter and Daily tasks. They give resources, speedups and hero shards, and they point you to the next building.
2. Start a new upgrade in every free building and research queue. Long timers go in before you log off.
3. Collect your Farm, Lumberyard, Herb Garden and Antitoxin Workshop output before the storage fills up. The resources page shows more ways to collect.
4. Join an alliance and donate to alliance technology. The alliance page explains help timers and shared bonuses.

New players can start with the beginner guide and come back here once the first Sanctuary levels are done.
