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:
| Category | How Points Are Earned |
|---|---|
| Enhance Raven | Feeding the Raven Guardian, consuming Raven Fruits, applying Essence, and opening Epigraph chests. |
| Train Soldiers | Mobilizing fresh recruits and promoting standing units into higher tiers. |
| Research Tech | Finalizing Laboratory technologies, increasing scientific Might, burning speedup minutes. |
| Build Territory | Completing structures, elevating Sanctuary level, increasing construction Might. |
| Enhance Heroes | Leveling 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!
- There is no separate “Power Hour” with double points — the entire event is structured as sequential 4-hour sprints.
- 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.
- 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:
- 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.
- 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.
- 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 / Action | Survival Battle | Alliance Duel | Optimal Strategy |
|---|---|---|---|
| Research | Badge milestone | Phase 3 (Wednesday) | Bank scrolls for Wednesday; clear Survival Battle using scroll-free tech nodes. |
| Recruit Tickets | 30-ticket milestone | Phase 4 (Thursday) | Spend exactly 30 tickets if milestone active; funnel remaining tickets to Thursday. |
| Training Speedups | Training milestone | Phase 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
- Audit your server’s unique mission rotation every Monday morning.
- Partition resources between Alliance Duel prerequisites and Survival Battle thresholds.
- Spend resources and speedups strictly within the matching active 4-hour phase.
- Clear training phases via top-tier recruitment (T7–T10) or promoting standing units.
- Sweep all milestone chests to secure your ~60,000 Skill Badges before the weekly reset (00:00 Server Time / 02:00 UTC).
