Alliance Championship is the game's flagship weekly cross-server tournament and one of the few events where coordination between alliance members directly drives outcomes. This guide covers the event's structure, registration mechanics, lane combat, tier progression, and rewards. Areas where mechanics are inconsistently reported or undocumented are flagged rather than guessed at.

Overview

Alliance Championship runs weekly on a fixed UTC schedule. Each cycle, an alliance is matched into a group of six and competes through five battle rounds, with combat resolved automatically based on registered marches across three lanes. Final placement in the group determines tier-based rewards and contributes to a longer-term star/tier progression.

Eligibility

For an individual to participate:

Furnace Lv. 10
Membership in an alliance
"Middle-ranking" status within the alliance, per the official requirement (the precise definition of "middle-ranking" is not specified in-game)

For an alliance to enter matchmaking, at least 10 of its members must have registered during the Sign-up Phase.

Weekly Schedule (UTC)

Phase	Window
Sign-up	Mon 00:00 – Wed 23:00
Matchmaking	Wed 23:00 – Thu 00:00
Preparation 1 → Battle 1	Thu 00:00 → ~11h prep, then 1h battle
Preparation 2–5 → Battles 2–5	Repeating cycle through Saturday
Final Battle ends	Sat 12:00
Completion Phase (rewards & shop reset)	Sat 12:00 – Mon 00:00

Each Preparation window is approximately 11 hours; each Battle round is 1 hour. The September 2024 patch shortened the Sign-up Phase to its current Mon–Wed 23:00 UTC window and moved Completion-Phase reward delivery earlier in the cycle.

Core Mechanics

These are the canonical numbers — strategy sections later in the guide reference back to these rather than restating them.

Mechanic	Value
Alliances per matchmaking group	6
Battle rounds per event	5
Lanes per battlefield	3
Lanes needed to win a round	2
Marches per lane that enter combat	Top 20 by score
Maximum fights per march per round	2

A lane is captured when all opposing combatants in it are eliminated. A round is won by capturing at least two of the three lanes. After two victories, an undefeated march is rotated out of its lane and the next allied march enters combat.

Squad Power for this event is calculated using a special formula that combines Hero Power and Troop Level. The exact formula is not disclosed in-game.

In March 2026, the in-event statistic previously labeled "Power" was renamed "Troop Power." If a re-registered squad has lower Troop Power than the previously registered setup, the UI now shows a warning prompt before the change is committed.

Sign-up Phase: Registration

During Sign-up, each participating player registers one march into one of the three lanes. Two registration details have meaningful downstream effects:

Fight order is determined by score. Within each lane, higher-scoring marches enter combat later. The strongest marches in a lane therefore engage opponents who have already burned through one or two fights.

Buffs are reportedly locked at registration. Buffs active at the moment a march is registered appear to be carried into the Battle Phase, regardless of whether those buffs are still active when the round begins. Re-registering — including after leaving and rejoining the alliance — overwrites the previous state, so any buff that wasn't active at the new registration moment is not captured. This behavior is widely reported but not stated in official UI text, and is best treated as the working assumption rather than a guaranteed mechanic.

Alliance changes during Sign-up:

A player who leaves their alliance and returns is reportedly required to re-register; their previous registration is reset.
A player who switches alliances after registering keeps their march fighting for the original alliance for that event cycle. They receive Completion Phase tier rewards from their new alliance and forfeit KO Rewards from the original.

A registered alliance cannot disband until the event concludes.

Preparation Phase: Lane Management

Each Preparation window precedes a Battle round and runs roughly 11 hours. Two functions matter here, both reported by community sources rather than officially documented:

Lane reassignment. R4 and R5 members can reassign which registered players go into which lanes. This appears to be the primary lever for adjusting between rounds.

Opponent intel. From Round 2 onward, an alliance can view the opponent's lane setup and power from the previous round. Round 1 is fought without this information. Note that this data is one round stale by definition — an opponent who shifted heavy marches to a different lane after Round 1 will not be reflected in what's shown for Round 2 prep.

The exact UI surface and any restrictions on reassignment frequency may differ in edge cases; the above reflects the dominant community account.

Battle Phase

Battles run for 1 hour. Combat is automated — there is no live tactical input during a round. Within each lane, registered marches fight in score order (lowest first). Each march can fight up to two times per round; a march that wins twice is rotated out and the next allied march in the lane queue takes its place. A lane is captured when all opposing marches in it are defeated. The alliance that captures at least two of the three lanes wins the round.

Tier System and Progression

Alliances progress through six tiers: Iron → Bronze → Silver → Gold → Diamond → Ultimate. Each tier is reported to have sub-tiers (I, II, III). Stars earned from event placement move alliances upward; stars can also be lost, and demotion is reportedly possible at Diamond and Ultimate. Exact star gain/loss thresholds per round outcome are not documented.

A persistent reward — the Alliance Championship Statue — unlocks at a Silver-tier milestone and provides gathering speed boosts to alliance members. Reported boost values are 3% (Silver), 5% (Gold), 7% (Diamond), and 10% (Ultimate), applying to Meat, Wood, Coal, and Iron. Sources disagree on the precise sub-tier (Silver I vs. Silver III) at which the statue first unlocks; the boost values are the working numbers, but the unlock threshold should be treated as approximate.

Ultimate-tier alliances reportedly receive a temporary cosmetic set — Knight of the Watch City Skin, Knight of Conquest March Skin, Knight's Glory Avatar Frame, and Knight's Glory Nameplate — for all members. These are time-limited (community sources consistently report 14 days), not permanent.

Rewards

Three reward streams come out of each event cycle:

KO Rewards (per round)

Granted automatically based on individual march performance:

KO 1 — march defeated 1 enemy march
KO 2 — march defeated 2 enemy marches OR remained undefeated when the round ended

A march that goes 2-0 and rotates out qualifies for KO 2 via the undefeated path. KO 2 is the higher-tier bundle.

Reported KO bundle contents:

Item	KO 1	KO 2
5-Min Research Speedups	10	15
10k Meat	20	30
10k Wood	20	30
1k Coal	40	55
1k Iron	10	15

Quantities are reported consistently across community sources but are not published in official documentation.

Completion Phase Tier Rewards

Granted at event close based on alliance final placement and current tier. Includes Championship Badges (event shop currency) and other materials. Specific badge quantities per rank are reported by some community sources but not officially published; the working assumption is that higher rank within higher tier yields more badges, but exact totals should not be relied on.

AC Shop

Resets weekly with the event cycle. The shop contains:

Fixed slots: Alloy, Polishing Solution, Pet Manuals, Hero Shards
- Design Plans are reportedly added to the fixed slots once a server reaches Generation 4
- The Patrick shards in the fixed slots are reportedly replaced by the Gen-2 hero's shards on Gen-4+ servers
Rotating slot: Pet materials, speed-ups, and additional manuals/shards, varying by player and cycle

The shop currency name varies across community sources (Championship Badge, Championship Token, Alliance Token); the in-game label may not match any single one of these consistently.

Constraints to Plan Around

A registered alliance cannot disband until the event concludes
A march can fight at most twice per round (see Core Mechanics)
Re-registering overwrites previously locked-in registration state, including any buff capture
Switching alliances mid-cycle preserves KO eligibility for the original alliance only

Strategic Considerations

The mechanics that produce the largest swings in outcome are registration timing, score-based fight order, and lane assignment.

Registration timing. Because buffs at the moment of registration appear to be carried into combat, registering during a window when an alliance has stacked buffs active produces a stronger registered state than registering immediately at Monday 00:00. The trade-off is that delaying registration leaves less time to identify members who haven't registered or marches with incorrect setups. The buff-lock behavior is widely reported but not officially documented, so plan around it as a working assumption rather than a guaranteed mechanic.

Score-based fight order. Higher-scoring marches fight last within their lane. The alliance's strongest registered marches will face opponents who have already absorbed one or two fights. The strategic implication: lanes often turn on the depth and consistency of mid-tier marches as much as on top-tier strength. A lane with one elite march and weak depth tends to lose in the late phase even if the elite march goes 2-0.

Lane management between rounds. R4 and R5 leadership can reshuffle which registered players go into which lanes during Preparation windows. Combined with opponent data from the previous round (visible from Round 2 onward), this enables a deliberate trade: overload one lane against an opponent's apparent weakness, concede another, and aim for the 2-of-3 round win. The information is one round stale, so this approach works better against opponents who don't actively shift between rounds than against those who do.

Fight cap and rotation depth. A march that goes 2-0 leaves the queue. Effective lane combat capacity is therefore constrained not just by the top of the registration list but by how many of the top 20 marches can chain wins. Lanes with shallow rotation depth tend to collapse late even when their leading marches are strong.

Specific troop and hero composition recommendations are widely circulated in the community but vary substantially across sources and are not mechanically verified, so they sit outside the scope of this guide.
