At a glance

4 barracks

each at a different level, each handling one promotion step.

Lv.5 → 9

Example of a full waterfall: train level 5 and promote up to level 9.

Day 5

The right time to run it: the Soldier Training day of the Alliance Duel.

The idea

Instead of upgrading all your barracks to the same level, you stagger them. You train low-level soldiers, then move them from one barracks to the next: each barracks handles a single promotion.

  1. Prepare: train level 5 soldiers in any barracks that can.
  2. 1st promotion: Lv.5 → 6 in the level 17 barracks.
  3. 2nd promotion: Lv.6 → 7 in the level 20 barracks.
  4. 3rd promotion: Lv.7 → 8 in the level 24 barracks.
  5. 4th promotion: Lv.8 → 9 in the level 27 barracks.

Which barracks for your Castle

Barracks levels are minimums. You can raise a barracks higher within its tier for more capacity.

CastleHighest troopTrain firstBarracks (levels)
Lv.10 to 13Lv.4Lv.13 / 6 / 10
Lv.14 to 16Lv.5Lv.13 / 6 / 10 / 14
Lv.17 to 19Lv.6Lv.26 / 10 / 14 / 17
Lv.20 to 23Lv.7Lv.310 / 14 / 17 / 20
Lv.24 to 26Lv.8Lv.414 / 17 / 20 / 24
Lv.27 to 30Lv.9 (10 with research)Lv.517 / 20 / 24 / 27

Before Castle level 10: barracks unlock at Castle 2, then you have one level 3 barracks (Castle 3 to 5), then 3 / 6 (Castle 6 to 9).

Day 5, minute by minute

Promoting a soldier by one level should score as much as training a soldier of that level: the same soldier going Lv.6 → 7 → 8 → 9 then pays four times.

  1. Monday to Thursday: train the base (level 5) nonstop, no speedups. If the troop limit is reached, training stops but promotions keep going.
  2. Friday, before starting: request the Royal Marshal favor.
  3. Start all four promotions at once: 5 → 6, 6 → 7, 7 → 8 and 8 → 9, each in its own barracks.
  4. Speed up, making sure nothing finishes in the last 5 minutes before the reset.
