New player — path to Sanctuary Lv.30 verified walkthrough · cross-checked vs wiki + compendium
Source: lastasylumwiki.com/docs/sanctuary-details/ + the Compendium's Sanctuary Details and Sanctuary Upgrade tabs. Last verified 2026-09-15.
TL;DR
- Build income first. A single Farm + Lumberyard + Herb Garden at Lv.1 is what lets you afford Lv.4 Sanctuary.
- Join an alliance before Sanctuary Lv.6. Lv.6 unlocks Alliance Hall; without it, every meaningful event is blocked and your progression stalls.
- Lab is the gate from Lv.11 onward. Every Sanctuary level past Lv.11 requires Lab at the previous level. Don't let Lab fall behind.
- Stack multi-instance income buildings. 2× Farms at Lv.12, 2× Antitoxin Workshops at Lv.16, more at Lv.26 — diamonds are best spent on income multipliers.
- Speed up during events. Elixir Scramble (Lv.15 unlock) and Expedition (Lv.16 unlock) recoup the diamond spend. Monthly Pass is the best $/diamond ratio in the game.
Three insights most guides miss
Diamond curve bends at Lv.21
Lv.16–Lv.20 diamond costs sit in the 2K–43K range. Lv.21 alone is 187,192💎 — and Lv.30 is 3.24M💎. Past Lv.20, diamonds are the real currency, not grain and timber. Stack every free source: Monthly Pass (best $/diamond ratio; also adds +5% Construction Speed since 2026-03-12), Expedition rewards, Era of Revival, Canyon Conquest, Alliance Duel points.
Lab is the real endgame gate
From Lv.11 onward, every Sanctuary level requires Lab at the previous Lv. If you have to choose between a Sanctuary level and the matching Lab level, Lab first — it's the prereq. The Planner shows the exact Lab target for your next Sanctuary level once you input your state.
Multi-instance buildings are the highest-ROI diamond spend
Two income buildings at the same level produce more than one maxed building. Lv.12 unlocks 2nd Farm + 2nd Lumberyard, Lv.16 adds 2 more Antitoxin Workshops, Lv.26 continues the pattern. Spend diamonds in this priority order:
- Permanent Build Queue ($1.99)
- 2nd Lab Research Queue ($9.99)
- Monthly Pass — every month, no exceptions

Bold rows are the pivot points — the levels where a major system unlocks or the cost curve bends. Base build times don't include Builder's Hut, Alliance Help, Noble Fortress (Lv.6), Monthly Pass (+5% since 2026-03-12), or research speedups. Real times are typically 30–50% shorter with buffs.
First-week plan
Day 1–2 — Foundation
~30 min active play
Build 1× Lumberyard, 1× Farm, 1× Herb Garden to Lv.1. Build Walls to Lv.3 (Sanctuary Lv.5 prereq). Reach Sanctuary Lv.5 by end of Day 2.
Day 3 — Join an alliance
1 hour of recruiting
Sanctuary Lv.6 unlocks Alliance Hall. Don't skip it — Cheese Trap, Alliance Duel, Elixir Scramble, and most alliance events are blocked without one. Recruit an active server-100+ alliance if you can.
Day 3–4 — Training Grounds up
~6h active + idle
Build 2× Training Grounds to Lv.4. Sanctuary Lv.7 prereq complete. Reach Sanctuary Lv.7 by Day 4.
Day 5–7 — 1st Lab up
~12h research queue
Level 1st Lab to Lv.7. This is the longest single upgrade before mid-game. Run it in parallel with Alliance Hall to Lv.5 and Walls to Lv.8. Sanctuary Lv.11 reachable by Day 10–14.
Day 7+ — Lockstep with Lab
daily check-ins
Push Lab in lockstep with Sanctuary from here. Stack 2nd Farm / 2nd Lumberyard at Sanctuary Lv.12. Use the Planner to keep both prereq chains green.
After Lv.15 — resource accumulation
Past Lv.15 the Sanctuary unlocks slow but the cost compounds fast. The Planner's input panel tells you exactly which +1 and +2 building to grind next, with the verified cost + time. The three highest-leverage habits for endgame are: keep Lab in lockstep with Sanctuary, stack multi-instance income buildings, and always be running one event (Elixir Scramble, Expedition, Canyon Conquest).
