Now live on #217.

• Registration — alliances sign up during the registration window.
• Matching — registered alliances are drawn into a group.
• Preparation — a fixed window before fighting opens, used to set rally leads and marches.
• Battle — runs 5 days, round-robin: each alliance in the group faces each of the others.
• Settlement — standings lock and rewards are distributed.

Requirements to participate

• Sanctuary Lv.10 or higher.
• At least 15 members must register in the alliance, or the alliance cannot participate at all.

Registration Phase

• Doctors register individually, choosing a lane (Left / Mid / Right) and setting up their own team — there is no alliance-wide auto-assignment.
• Registered teams do not occupy march queues, and soldiers will not die in Canyon Conquest — it's a consequence-free format for troop losses.
• Max troops per lane scales with the alliance's league tier (see table below); within that cap, higher-Might teams participate first.
• Once the alliance enters, every registered member gets rewards — including those who registered but didn't end up participating. Unregistered members get nothing.
• If a registered member leaves the alliance after the matching phase begins, their troops still fight, but that player receives no reward.

Matching Phase

• Six alliances of similar league rank are grouped randomly. Fewer than six still forms a group; an odd alliance count gives one alliance a bye, which counts as an automatic win that round.
• Registered alliances cannot be disbanded before the Conquest ends.

Preparation Phase

• Format is group round-robin: each alliance fights each of the other five in its group separately, five rounds total.
• A preparation window precedes each round. Leaders and Officers can move all troops from one lane to another, or reassign a single team — but once the window ends and battlefield cleanup begins, no further redeployment is allowed until the next round's prep window.

Battle Phase

• Both alliances compete across 3 lanes for 3 flags simultaneously.
• Combat is a relay: teams on each lane fight in turn, the winner carries remaining troops into the next fight. Each team can only fight a maximum number of times before being forced out — 2 fights at Rookie/Novice/Beginner league, 3 fights at Elite league and above.
• First side to clear all enemy troops on a lane wins that lane's flag. Most flags captured wins the round (3 points); an even split is a draw (1 point each).
• Fight order within a lane is fixed: teams enter combat sorted by Might, lowest to highest, and this order cannot be changed once set.

Settlement Phase

• After all 5 rounds, alliances are ranked by total points within their group; ties are broken by the alliance's total deployed troop Might.
• Per-round rewards (victory/defeat) are issued based on that round's result, and separate kill rewards are issued based on enemy troops each doctor's own troops defeated.

League tiers

"Kill limit" here is the in-game label for fights-per-team before forced exit (see Battle Phase above), not a literal cap on kills. In each battle, a team that reaches the max enemy-troop-kill count for its tier is also forced to exit early.

Live example, Novice League registration screen: 1,000 trophies shown as the league's own threshold display; the alliance's registration count read 57 against the 15-member minimum — comfortably clear. A separate live deployment screen for a 15-cap (lower league) lane showed Left Lane at 20/15 registered (158M Might), Mid at 19/15 (156M), Right at 19/15 (156M) — confirming registration can exceed the participation cap, with the top-15-by-Might actually fighting and the rest still credited for registering.
