In Last War, growth speed depends on “when” you act more than “what” you do. The same action on the theme day scores rewards too; off-theme it scores zero. Details: Arms Race · Alliance Duel.
One-line principle
Hoard resources, then dump them on the “theme day.” Build/research/training/hero upgrades/drone parts each have a day they score. Aligning to the calendar handles growth + Arms Race + Alliance Duel with the same resources.
Weekly calendar (big picture)
| Cycle | Event | Core |
|---|---|---|
| Daily | Arms Race | 6× 4-hour segments. Match actions to the phase → main Skill Medal source |
| Mon–Sat | Alliance Duel (VS) | Daily themes for 6 days. 7 points to win. Spend on the theme day |
| Biweekly | SvS (Server vs Server) | Prep (Sun–Fri) + Capital battle (Sat). Valor Medals → Black Market orange gear |
| New 1 week | Marathon | 7-day new-player mega event, final goal HQ17 (7-Day Roadmap) |
| In-season | Global Expedition, etc. | In Season 6, weeks 2/4/6 give free awakening shards (Season Guide) |
Key sync: time your Alliance Duel tasks to opening Arms Race chests. Spend speedups/recruits/upgrades on the day’s theme to hit Duel score + Arms Race phase rewards + real growth at once.
”Spend day” by resource
| Resource/action | Where it scores |
|---|---|
| Build/research/training speedups | Alliance Duel theme day / matching Arms Race phase |
| Drone parts · battle data | Alliance Duel Day 1 (Mon) — hoard all week, dump Monday |
| Hero EXP/shards/skill medals | Alliance Duel Day 4 (Thu) — save and dump Thursday |
| Combat (attacks/kills) | Alliance Duel Day 6 (Sat) + SvS battle |
Common mistakes
- Burning speedups on a non-theme day → zero score. Check the calendar first.
- Spending drone parts/shards as you get them → stacking on Mon/Thu spikes Duel score.
- Neglecting the SvS prep week → lose the invasion right, Saturday decided before it starts.
- Over-investing in Arms Race → just clear the minimum for phase rewards, save main resources for the decisive Duel stages.
