Quick Answer
Immortal Arena uses three marches in a best-of-three contest. Build enough strength to win two matchups rather than placing every useful asset in one exceptional march. Once two wins are reliable, evaluate whether a third win is achievable: the 1.23.900 update added bonus points for winning with all three marches.
This is a guide to the documented Immortal format within the wider Apex Arena feature. Do not transfer its entry limits, attempts or casualty rules to Rookie Arena or another similarly named mode.
Entry and Event Format
The May 2025 reference format separates an active stage from an off-season and admits Chiefs in the top 200 of their state's Solo Power leaderboard. It requires three configured marches, automatically uses the highest-level troops available, and describes combat without troop harm.
It lists ranking, daily and alliance rewards. It also describes up to 20 daily challenges, but that should not be read as 20 free attempts: free and premium allowances have changed, including a PTR adjustment announced in 1.23.900.
Use the eligibility and attempt counters on your current panel. If you cannot enter, check the particular mode, state rollout, ranking requirement and active/off-season status before spending on Power.
Build Three Complete Marches
Open each march separately and inspect its assigned heroes and supported assets. A strong main preset can hide an empty slot or missing equipment in the second and third teams.
| Check | Why it matters |
|---|---|
| Hero class and development | An unbuilt replacement can weaken a previously usable team |
| Military skill version | Completion enhancement can change how the formation works |
| Hero Gear and Tempest Arms | Missing or changed assignments can distort the comparison |
| Pets and eligible support | A forgotten assignment can leave one team short of the planned benefit |
| Behemoth and other mode-supported systems | Check what is actually available to each lineup |
| Saved formation | Confirm the final selection rather than relying on a preset name |
Use the Hero Gear guide when an equipment slot needs work. Do not buy a new hero to solve a problem caused by an existing hero entering without its intended equipment.
Two Wins First, Then the Sweep
Best-of-three scoring changes the value of concentrating all development in one team. Winning one matchup by a huge margin still leaves two losses as an overall defeat.
Consider an illustrative opponent comparison:
| Your setup | Matchup 1 | Matchup 2 | Matchup 3 | Result |
|---|---|---|---|---|
| Everything concentrated in one march | Comfortable win | Clear loss | Clear loss | 1–2 defeat |
| Two supported marches | Narrow win | Narrow win | Clear loss | 2–1 win |
| Three matchups you can realistically win | Win | Win | Win | 3–0 win and applicable sweep bonus |
This is a strategic example, not a simulated damage model. Moving equipment or heroes does not guarantee those outcomes. Use it to decide which weak point deserves investigation.
Avoid sacrificing a reliable second win simply to chase an uncertain third. A 3–0 bonus matters only when the formation can actually deliver the sweep.
Read the Opponent Before Reordering
Inspect the visible lineup and prior reports. Identify the actual effects of the enemy heroes rather than inferring strength from a portrait or total Power alone.
Later heroes can be built around Berserk, Resilience or Control styles. Those are not synonyms for Infantry, Rider and Hunter. Do not apply an invented three-troop counter triangle to the Arena, or assume every hero of one generation uses the same style.
If the preview and battle history show a consistent pairing you can improve by reordering, test that change deliberately. Keep the roster and equipment otherwise stable so the next report can explain what changed. Where a tooltip has conditional damage or combo effects, check that your lineup satisfies them.
The generation reference helps identify the roster, while the hero's current military skill text determines what the build actually does.
Turn One Loss Into a Useful Adjustment
After a defeat, review all three reports:
- Record which matchup lost and whether it was close or decisive.
- Check the deployed heroes and equipment first.
- Compare troop information, applicable stats and skill effects.
- Identify one plausible cause: missing development, an unfavourable interaction or an incomplete assignment.
- Change one variable and compare against a similar opponent.
Do not respond to every loss by increasing all three marches' Power indiscriminately. If two teams win and the third loses, your next goal differs from a setup losing all three.
The battle report walkthrough explains how to compare like-for-like fields without pretending that one attack percentage fully describes a battle.
Attempts, Rewards and Stopping Points
Use the available free attempts before deciding whether another challenge is worth a premium cost. A paid attempt needs a plausible result: an attainable reward threshold or a matchup you can now improve.
Record the reward cutoff and reset timer. Ranking can change after you log out, so a temporary position is not the same as a secured final reward. Claim daily rewards separately from end-of-stage rewards.
The documented spectator feature allows support for the top three players, including during the off-season, with a small Biocap reward. Check the available like/support buttons even when you are not actively fighting; do not confuse that claim with eligibility to challenge.
Hero's Badge Coins associated with Arena rewards belong to the Honor Store system. They are not the ordinary rarity-matched Hero Badges used in classic hero ranks. Read the currency name before planning an exchange.
F2P and Spender Tips
F2P: assemble the best three teams your existing roster can sustain, fix missing assignments and use reports to choose realistic opponents. Do not spread scarce materials across nine heroes solely to make every portrait look equally developed.
Spenders: identify the matchup an upgrade is intended to change. Completing a coherent second team can matter more than further increasing a main march that already wins comfortably, but the correct choice depends on your actual reports.
Common Mistakes
- Treating one overpowering march as enough to win a best-of-three contest.
- Reading the maximum daily challenges as a guaranteed free allowance.
- Forgetting equipment or support on a secondary lineup.
- Confusing hero combat styles with troop classes.
- Applying Immortal's no-harm rule to another event.
FAQ
How many marches do I need? The documented Immortal Arena format requires three and resolves the contest best of three.
Do I need to win all three? Two wins take the contest. The updated format also rewards a three-march sweep with bonus points.
Why can I not participate? Check the current eligibility and stage. The May 2025 format used the state's top-200 Solo Power requirement; other arena modes have their own rules.
Will these battles kill my settlement troops? The documented Immortal format describes no troop harm. Confirm that you are entering that mode before applying the rule.
Key Takeaways
- Prepare three complete lineups and aim for two reliable wins.
- Pursue sweep bonuses only when the third win is realistic.
- Use the current attempt counter and all three battle reports to guide spending.
