Kingdom War is a battle of servers (kingdoms). Like the Alliance Competition, it runs in two stages: first the kingdoms collect points for a week, then on Saturday comes the battle for the Royal City.

The bracket and who wins
Up to 8 kingdoms are put into a group and split into pairs. The winner moves on along the main bracket to the final, the loser is not knocked out but keeps fighting other losers. In the end one champion remains.

The winner is decided by the battle for the Royal City. The point stage decides only the roles: who defends their own Royal City and who flies in to capture someone else's.
- The attacker wins if they capture the defender's Royal City 100%.
- The defender wins if the city is still not fully captured after 4 hours of assault. Even if the defender lost on points, a held city is a win.
The points stage
From Sunday to Friday the kingdoms collect points. On Saturday at 00:00 the count ends: the one with more points attacks, the one with fewer defends.

| for what | kingdom points |
|---|---|
| an alliance win in the daytime stage of the Alliance Competition | +30,000 per alliance |
| the best player (MVP) of the Alliance Competition | +6,000 |
| Demon King Blight: kingdom win by total damage | +250,000 per day |
| Demon King Blight: 1st place by personal damage | +150,000 |
| a plundered caravan of an enemy kingdom | +120 |
| 1st place in the Survival Battle | +2,200 |
| a win in Elixir Scramble | +50,000 |
Notes:
- Points for the Alliance Competition, MVP, the Demon King and the Survival Battle are credited the next day.
- Demon King Blight is a world boss (Warlock, Ranger, Warrior). You get 10 attacks a day, and the author advises every player on the server to spend all 10: 250,000 points are decided by the kingdoms' total damage. According to the author, the damage of the kingdom's top 200 players counts.
- Caravans are plundered the same way as in a Covert Operation on another server: open Caravan Trade, find the rival server's caravan, go to its server and look for golden caravans on the world map. You can plunder 4 times a day.
- Survival Battle: no kingdom points are given if 1st place has fewer than 1,000 Survival Battle points or the Sanctuary is below Lv.15.
- Elixir Scramble: an alliance has two teams, and each winning team brings its own 50,000 points.
Saturday: the battle for the Royal City
| time (server) | what happens |
|---|---|
| Saturday 00:00 | point stage ends, attackers and defenders are set |
| Saturday 00:05 | attackers can relocate to the defenders' kingdom |
| Saturday 12:00 | protection comes off the Royal City and the turrets, Royal City Scramble begins |
| Saturday 12:00-16:00 | the assault, the winner is decided |
| Saturday 24:00 | final rankings, rewards by mail, everyone returns to their own kingdoms |
During the battle, players of one kingdom do not fight each other inside the Royal City and the turrets: you can only fight the rival's troops.
Turrets. Around the Royal City stand 4 turrets: East, West, South and North. A captured turret hits the Royal City every 10 seconds if an enemy holds it, destroying part of the garrison. Every 5 reinforcement squads in a turret shorten the interval by 1 second, down to a minimum of 4 seconds. If your kingdom holds both the city and the turrets, the time to fully capture the city drops sharply.
Personal points and rewards
In the battle for the city, a player earns points on their own (the "Points Acquisition" window): for destroyed soldiers of the enemy kingdom (the most in the Royal City or a turret), for every second in the garrison of the city or a turret, and for lowering the enemy city's defense. Points drive the personal ranking and the stage rewards.

Win streak rewards. The winning kingdom gets a victory reward, a win streak doubles it, and a loss breaks the streak. Only players with more than 50,000 personal points can claim the streak reward.

Kingdom rewards go to all players by the kingdom's final place in the bracket:
| place | participation reward |
|---|---|
| 1 | Curio Chest (UR) ×3, Universal Curio Shard ×18, Grain / Timber / Herb Level Supply (UR) 18 each, Fame Medal ×55,000, Avatar Frame "Legion of Glory" (7d) |
| 2 | Curio Chest (UR) ×2, Universal Curio Shard ×16, supplies (UR) 16 each, Fame Medal ×45,000 |
| 3 | Curio Chest (UR) ×1, Universal Curio Shard ×14, supplies (UR) 14 each, Fame Medal ×35,000 |
| 4 | Curio Chest (UR) ×1, Universal Curio Shard ×12, supplies (UR) 12 each, Fame Medal ×30,000 |
| 5 | the same, 10 each, Fame Medal ×27,000 |
| 6-8 | the same, 8 each, Fame Medal ×24,000 / 22,000 / 20,000 |
The King of the winning kingdom gets the Avatar Frame "King of Battle" for 13 days.

King of Battle
If a kingdom wins as the attacking side, its king becomes the King of Battle, and new positions appear in the kingdom:
| position | bonus |
|---|---|
| King of Battle | hero HP, ATK and DEF +10%, enemy troop mortality in PvP +5% |
| Chief of War | overall march speed +5%, enemy troop mortality in PvP +5% |
| Chief of Affairs | construction and research speed +60% |
The king can also hand out King of Battle chests: Mythic God of War Chest ×1, Honor Vanguard Chest ×5, Fearless Hero Chest ×10 and Logistics Support Chest ×20 (Diamonds, Recruit Tickets, resource supplies).
The rewards are decent even just for taking part, and the winners' are noticeably better - so it is worth giving it your all as a whole kingdom.
