Thief Hunt is the alliance stamina event: you spend stamina attacking thieves on the map, and thief kills roll for a chance to spawn a Thief Leader boss the whole alliance can rally. It converts your spare stamina into the exchange shop — one of the best value shops in the game if you buy it in the right order.
This guide covers boss spawn mechanics, the technique for spawning high-level bosses, the exchange priority list, and the boss squad.
How It Works
- Attack thieves on the map with stamina. Kills spawn the Thief Leader boss for an alliance rally — the spawn is rolled per thief killed, not per event day or per player.
- Bosses spawn on the first kill or after 20 — the roll happens early or after a streak. One alliance reports always 8 or more; expect variance and keep killing.
- Points and rewards do not increase later in the event. There is zero reason to hoard stamina — spend it immediately to roll for the big bosses sooner.
Boss Levels & Alliance Cap Progression
| Server age | Common boss levels |
|---|---|
| New servers | 10 / 15 / 20 / 25 / 30, rarely 35 |
| Developed servers | 40 / 65 / 80 / 85 / 90+ |
- How Level Cap Increases: Max discoverable Leader level increases after the highest Leader is defeated 3 times by your Alliance members (July 30, 2026 update).
- Discovery Ownership Rule: The Leader Level Cap only increases when Leaders discovered by your Alliance are defeated by your members. Defeats by other Alliances do not affect your level cap (July 2, 2026 update).
- Chief’s Coin Chest: Lv.80+ Thief Leaders now drop a valuable Chief’s Coin Chest, awarded directly to both the discoverer and the Rally initiator!
- Boss levels scale with the server development stage — high-age servers will no longer see low-level spawns.
The Nonstop-Kill Technique for Level 30/35
The verified technique for pushing boss levels to 30 and 35:
Kill thieves one by one WITHOUT letting your troops return to base — nonstop, back-to-back marches with zero idle time.
Marches returning to base break the streak; consecutive kills roll the spawn repeatedly. Chain your targets so the next march leaves the moment the last one lands, and the high-level spawns come far more often.
The Exchange Priority List
The exchange shop is the real reward, and the community consensus order is stable:
Week 1 Only
- Scrolls — 4 for Alliance Duel tech, then never again. Duel tech wants exactly four; after that they are dead weight.
Always, Every Event
- Raven Essence — every event, no exceptions. The Raven system is permanently bottlenecked on it (see the Raven guide).
High Priority
- Stamina
- Speedups
- Raven chest
- Epigraphs when available
Late Game
- Herbs — never enough of them; late-game accounts buy herbs every event.
Alternative Priority List
- Stamina
- LV3 Raven chest
- Blue/purple epigraph chests
- Research/construction speedups
- Recruitment tickets
And one inventory rule: the scroll limit carries over event to event. If you hit the scroll cap, that cap follows you into the next event — another reason the “four then never again” rule exists.
Field Tips (Korpez)
- Park one squad at a dense pack of small thieves and chain them — 10 kills in ~2 minutes is what fully feeds your spawn counter. Standing still between spawns beats roaming.
- Kill your own alliance’s bosses first — if you drag your feet, a neighbor alliance will clear your bosses and rob your whole team of the damage-reward shares. A lose-lose you somehow chose.
- Oversized boss? Recruit up. Drop the boss link in alliance chat — a whale or a whale-leaning mid-tier will absorb the kill, and you keep the drop rewards. Never let a high-level Thief Leader despawn.
- Keep one squad home permanently for ally rallies — joining costs you zero stamina, but you still bank the full reward share. Free loot for zero resource. This is the best one: don’t leave it unharvested.
- An hour of targeted grinding converts to roughly 4K Thief Coins, 250K Crow berries and ~65M grain+wood+herbs in resources — which is why this event outearns the Dwarven Mine in raw weekly income for most players.
The Boss Rally Squad
The community boss comp, built for damage over time:
| Row | Heroes | Job |
|---|---|---|
| Front | Arthur + Bella | Survive longer — every extra second of survival stacks more damage |
| Back | Marlena + Shadow + Claire | Damage engine behind the frontline |
The logic: longer survival = more damage stacked. A boss fight is not a burst check — the squad that stands the longest deals the most, so prioritize survival over raw attack. Full hero details are in the Heroes guide.

❓ FAQ — Frequently Asked Questions
What is the best F2P team in Last Asylum: Plague?
The canonical F2P squad is Arthur, Daskal, Marlena, Harper, Claire (all Warriors — mono-faction gives +20% HP/ATK/DEF). Arthur is free from day 1; the $1 Marlena top-up is considered the best value in the game. Daskal arrives in the first Era of Revival season (day 120+).
What should I upgrade first?
Sanctuary first, always — it gates every other building and your hero level cap. Then Training Grounds, Barracks, Research Lab, Infirmary, Wall. Keep the Builder’s Hut at Sanctuary level until Sanctuary 15 for free construction speedups.
When does Marlena unlock?
Day 66 for free — or immediately via the $1 starter top-up. Save UR shards so she lands at 8★ right away, then push 10★.
How do I get Cynthia as F2P?
Cynthia arrives via the Wishing Wheel on day 8. Save diamonds from day 1 (skip everything else) — ~11,500 diamonds total, and always spin ×10 (single spins waste tokens).
How do I get antitoxin?
Antitoxin Workshop + Stable production, every building upgrade completion, Falcon Quests (nearly all of them), Covert Ops and Caravan Trade (including plundering others’ ops — up to 5/day), and Blight/Elite Blight hunts (10/20 stamina). Events pay large amounts.
Why did my plunder income drop to almost nothing?
You hit the daily plunder limit: below the limit 100%, from 1× the limit you keep only 15%, from 1.3× only 5%. It resets at 02:00 UTC. The limit scales with Sanctuary level (2.5M at Lv.10–12 up to 30M at Lv.30) and rises immediately when you upgrade Sanctuary. A yellow triangle under your Might shows the status.
What should I buy in the shops?
Sanctuary/Expedition/Alliance shops: Crow Essence and UR Hero Omnifragments first. Honor shop is for gear blueprints only (never epigraph chests there). All shops restock Monday.
Are diamonds worth spending on speedups?
Only the VIP-shop 8h speedups are considered acceptable purchases — and only after hero resources. Community rule: never dump diamonds into speedups over hero wheel events (Cynthia day 8, Joker after day 15).
What faction should I build?
Warriors are the best early game (free Arthur/Harper shards, $1 Marlena). Rangers peak mid game (counter Warriors). Warlocks are the best late game but need heavy long-term investment. Mono-faction (5 heroes of one type) is the current meta because UR epigraphs buff a single faction.
How does Claire SSR→UR conversion work?
Opens on Era Day 8. She lands at 6★ and the run to 10★ costs 1,600 SSR shards (each substage costs 2× the SSR price). There’s a team-buff dip between 6★–9★ — skip it by banking Hall of Honor levels before converting (Lv.60→8★, Lv.100→9★, Lv.160→instant 10★).
How do I redeem gift codes?
In-game: Avatar (top-left) → Settings → Gift Code. iOS or web: log in at the official redemption page with your linked Facebook/Google account, pick server and character, enter the code.
What are the biggest beginner mistakes?
Upgrading everything equally instead of one main squad; judging heroes before high stars (Marlena is the classic late bloomer); splitting Awakening materials across heroes; wasting gems on VIP levels over hero wheels; skipping daily plunder (~27M resources/day); letting stamina cap.
