Use Spar to test a new deputy or a different back line before exposing the army on the World Map. You select one of your formations and face another ranked player's strongest team. This is a useful formation experiment; it does not replace preparing real soldiers, positioning and march conditions for a siege.
Find a matchup that answers your question
Open Rankings, select Personal, then the Power ranking. Each entry represents that player's highest-Power team with a commander, rather than the sum of every army. Inspect the player's team, heroes and equipment. To test whether your back line survives, choose an opponent whose damage pattern is relevant, rather than relying only on a similar Power number.
- Select Spar on the opponent to open the two-team confirmation screen.
- Use Formation to choose your army. Check that its commander is still assigned, then check deputies, positions and equipment.
- Inspect the position display for both sides. If the opponent may have changed teams, use Update to fetch their latest strongest formation. Wait if that button is on cooldown.
- Read your remaining daily attempts and start. Both teams need a commander. An attempt is consumed when a battle actually takes place, whether you win or lose; a failed eligibility check does not consume one.

What the loss-free conditions mean
Spar consumes no hero stamina and causes no real soldier losses. It supplies the highest soldier tier you have unlocked and each hero's maximum soldier capacity. Injured, exhausted or deployed World Map troops do not prevent this test. You are comparing formations at full strength; a depleted army outside the city cannot be expected to reproduce that result.
Power reflects hero levels, stars, skills, equipment and city technology. Losing to a lower-Power opponent calls for checking counters, positions and skill triggers. It does not automatically indicate a ranking error. The list ranks Power; winning a Spar battle does not directly exchange your ranking position with the opponent.
Change one thing, then read the report
Begin with your existing formation. Note whether the commander survives, which back-line hero takes damage and how the important skills interact. Then change a single position or piece of equipment and compare. The Report button on the Power ranking opens dedicated Spar records and replays. Separate repeated patterns from occasional triggers: one successful control effect is not enough to establish that a formation is reliable.
Completed matches provide their configured rewards. Defeating a higher-ranked opponent can grant an additional challenge reward; losing or defeating a lower-ranked opponent gives the baseline reward. Plan experiments around your remaining attempts, and use the information already visible in reports before spending another attempt.
Fix a disabled battle button
A previously selected army can remain in your selection history after its commander is removed. Open Formation again, assign its commander or select another eligible army. If the opponent has no valid commander in any team, updating can leave their display empty; choose another opponent. A daily-attempt warning is a separate limit: inspect the counter and any available privileges rather than changing teams in the hope of resetting it.
Continue with reading battle reports to identify damage sources, then use the formation guide to make the adjustment.
