Alliance Duel is won by saving the right item for the right day. Do not open drone, hero, component, research or training resources when they enter your inventory. Reserve them, pair the spend with the matching Arms Race phase, claim the daily chests, and prepare shields and teleports before Day 6.

| Day | Common focus | Save before the day | Do not waste |
|---|---|---|---|
| Mon | Radar / drone | Radar tasks, drone data and parts where eligible | Claiming radar rewards too early |
| Tue | Base expansion | Construction and research speedups, Valor-related progress | Finishing long builds before reset |
| Wed | Science / heroes / components | Hero recruitment, shards and component chests where listed | Opening component boxes on another day |
| Thu | Hero progression | Skill medals, EXP and hero resources | Leveling bench heroes for weak points |
| Fri | Total mobilization | Broad reserve and leftover efficient upgrades | Draining Day 6 protection resources |
| Sat | Enemy Buster | Shields, teleports, stamina, hospital capacity | Unplanned attacks and exposed bases |
The best spend advances three goals: permanent account growth, a VS chest and an Arms Race reward. If only one of the three applies, delay the item unless it blocks progress. Construction and research timers are easiest to plan; start the timer early and finish it inside the correct scoring window.
| Before reset | During combat | After objectives |
|---|---|---|
| Empty exposed marches, check shield duration, hospital and teleport stock | Attack only assigned targets; watch war fever before shielding | Heal within capacity, re-shield and stop feeding points |
A member who cannot be active should shield before the window. A member who can fight still needs a return route and hospital limit. Day 6 points are never worth losing more troops and resources than the reward returns.


Lock the day and scoring target first; compare Last War options only for the remaining gap.
Alliance Duel becomes manageable when every item has a day before it is spent. Reserve by category, double-dip with Arms Race, secure the chests the alliance actually needs and treat Day 6 survival as part of the score.
