Hero vs Demon King Battle
Nations are divided into the Hero Faction and the Demon King Nation to wage war against each other.
The Hero vs Demon King Battle, which is Phase 3, begins after the maintenance that concludes the Magic Stone Battle.
When the Magic Stone Battle ends, the nation with the second-highest resource investment becomes the "Demon King Faction," while all other nations become the "Hero Faction."
The leader of the Knight Order that possesses the Magic Stone in the Demon King Nation becomes the "Demon King," and the stronghold containing the Demon King Nation's Magic Stone becomes the "Demon King Castle."

In addition, up to one stronghold owned by each Knight Order in the Demon King Nation becomes a "Demon Tribe Stronghold" when the specified conditions are met.
Each Knight Order must invest 100,000 Sp of resources to create a Demon Tribe Stronghold.
The Demon King's power is immense.
Raise your Knight Order Lv and conquer the Demon Tribe Strongholds one by one to weaken that power.
【Flow of War】
A new Stronghold Battle period is added after the Phase 2 Magic Stone Battle.
During this period, the Demon King Nation and the Demon King descend upon the World, but players cannot march on Demon Tribe Strongholds or the Demon King Castle.
After the battle enters Phase 3, Hero vs Demon King, players can no longer march directly on the Demon King Castle.
You must destroy the barrier around the Demon King Castle generated by Demon Tribe Strongholds before you can march on the castle.
In addition, actions that change membership, such as creating, joining, leaving, or disbanding Knight Orders and Grand Alliances, become unavailable.
Wars can be conducted in the following order.

After declaring war and before the battle begins, dispatch parties to the stronghold that will serve as the battlefield.
The parties gathered at the stronghold then fight to determine victory or defeat.
