Survival Battle (internally arms_race in game code) is the premier recurring mission event in Last Asylum: Plague, serving as the financial bedrock for free-to-play commanders: diligent F2P players consistently pull roughly 60,000 free Skill Badges every single week, along with Survival Seals (arms_race_daily_point_item).

Skill Badges are the permanent bottleneck across all hero skill trees. This guide breaks down the 4-hour rotating phases, milestone rewards, and seamless coordination with Alliance Duel phases.


⚙️ Event Mechanics & Task Categories

  • Survival Battle runs in continuous 4-hour phases (as directly verified by the in-game Quiz of Wisdom: “How many hours does each Survival Battle last in the game? — 4 Hours”).
  • Every 4 hours throughout the day, a new developmental track activates.
  • CRITICAL NOTE: Exact task rotations and schedule orders vary by server, so always audit your active event tab.
  • The event revolves around 5 core developmental categories:
CategoryHow Points Are Earned
Enhance RavenFeeding the Raven Guardian, consuming Raven Fruits, applying Essence, and opening Epigraph chests.
Train SoldiersMobilizing fresh recruits and promoting standing units into higher tiers.
Research TechFinalizing Laboratory technologies, increasing scientific Might, burning speedup minutes.
Build TerritoryCompleting structures, elevating Sanctuary level, increasing construction Might.
Enhance HeroesLeveling heroes (Antitoxin), upgrading skills (Skill Badges), and star ascension (Omni Shards).

⏱️ 4-Hour Phase Mechanics: Avoid Wasted Resources

The central operational rule: never spend high-value resources outside the active matching phase!

  1. There is no separate “Power Hour” with double points — the entire event is structured as sequential 4-hour sprints.
  2. Points are awarded only for actions that match the currently active 4-hour category. If “Train Soldiers” is active, building or research speedups contribute zero event points.
  3. Deploy building, research, and training speedups strictly when the 4-hour Survival Battle phase aligns with the active Alliance Duel day (e.g., building speedups on Tuesday during “Build Territory”). This allows you to double-dip milestone chests and alliance score simultaneously!

🛡️ Soldier Training: Tier Scaling & Promotion Strategy

[!WARNING] Common Beginner Mistake: Training T1/T2 for “Headcounts” In Survival Battle, points earned from training soldiers scale directly with troop tier (from Lv.1 to Lv.10). T1 and T2 units yield negligible points — attempting to clear high-milestone chests with low-tier troops clogs barracks queues and wastes food without moving the point needle.

Optimal approaches for the “Train Soldiers” phase:

  1. Train your highest unlocked tier (T7–T10): High-tier units grant exponentially more points per soldier. A few full queues of your top tier will unlock milestone chests far faster than thousands of T1 recruits.
  2. Utilize Promotion (Upgrade Existing Troops): To rapidly reach the next chest before the 4-hour window closes, promote previously trained lower-tier units to your highest unlocked tier (e.g., T7 → T8 or T8 → T9). Promotions take only a fraction of the time needed for fresh recruitment and yield the point differential between tiers.
  3. Pre-queue Long Batches: Start training top-tier batches ahead of time so they complete right as the 4-hour training phase begins, claiming instant points without burning speedups.

🦅 Monster Hunts: Hoard Raven Fruits

  • Conserve Raven Fruits: Do not burn fruits on off-days when no event points are attached to monster purges.
  • Spend Natural Stamina: Natural stamina regenerates continuously — bleed it strictly inside active monster elimination windows.

🎫 The 30-Ticket Recruitment Milestone

A standout high-efficiency milestone clears for exactly 30 Recruitment Tickets. If banked, trigger it immediately for an effortless chest sweep. If ticket-constrained, evaluate whether to hold for Thursday’s Alliance Duel Phase 4 (+3,450 points per recruit).


⚔️ CRITICAL: Alliance Duel Synchronization

The central F2P tactical balance: managing resource contention between Survival Battle milestones and Alliance Duel phases.

Resource / ActionSurvival BattleAlliance DuelOptimal Strategy
ResearchBadge milestonePhase 3 (Wednesday)Bank scrolls for Wednesday; clear Survival Battle using scroll-free tech nodes.
Recruit Tickets30-ticket milestonePhase 4 (Thursday)Spend exactly 30 tickets if milestone active; funnel remaining tickets to Thursday.
Training SpeedupsTraining milestonePhase 5 (Friday)Unleash major training speedup reserves on Friday (+100% points, +30% speedup value).

Golden Rule: When calendars conflict, prioritize the weekly 60,000 Skill Badges milestone floor — there is no equivalent renewable badge farm anywhere in the game!


📋 Weekly Survivor Checklist

  1. Audit your server’s unique mission rotation every Monday morning.
  2. Partition resources between Alliance Duel prerequisites and Survival Battle thresholds.
  3. Spend resources and speedups strictly within the matching active 4-hour phase.
  4. Clear training phases via top-tier recruitment (T7–T10) or promoting standing units.
  5. Sweep all milestone chests to secure your ~60,000 Skill Badges before the weekly reset (00:00 Server Time / 02:00 UTC).
