Knight Online Castle Siege: what is CSW?
CSW is the event in which clans fight to take a castle. On ChromeKO, this battle is fought for Delos castle. A castle siege is not won by individual strength alone. Good organization, a clear division of roles and clan teamwork decide the outcome.
Because CSW is a clan battle, joining a clan is the most natural way in. If you do not have a clan yet, have a look at our clan guide first. Clans show their identity with clan capes, and that identity stands out in castle sieges too.
Delos castle and its owner
Delos castle has an owner clan. The clan that holds the castle benefits from its tax income. The tax system, the current state of the castle and the current owner are shown on the war page. We do not write tax rates or income amounts in this guide, because these details can change.
Owning the castle means your clan is in one of the most noticeable positions in the game. The clan ranking is on the clans page. Reading the owner clan together with its place in the ranking helps you see how active each clan is.
King election and why it matters
Each nation has a king, and the king is chosen by election. The king has a voice in the management of the nation and in its decisions. Castle Siege and the king election are linked, because who holds the castle also affects how the nation is run.
You can find out who the current kings are and the state of the election on the war page. Before you vote, check the latest status of the candidates so you can make an informed choice. If your clan takes part in the election, discuss in advance which candidate your members support and why. Decisions made together are easier to follow.
How do you prepare for a castle siege?
A plan before the siege makes a real difference:
- Start with your clan. It is very hard to take a castle alone. Move together with your clanmates.
- Follow the event time. The times are listed on the event page. The server staff set them and they can change, so check the page regularly.
- Decide on roles. Agree in advance who coordinates, who leads the attack and who supports.
- Get ready. Check your potions, spare items and inventory. A siege can last a while, so missing preparation makes it harder.
- Check your connection. If you play in the browser, a steady internet connection matters. On a phone, hold it sideways.
If you are new to the game, learn the basics first with the beginner's guide. That gives you more confidence in a castle siege.
How is it different from BDW?
BDW is a nation war, so your character's nation is what matters most. CSW is a war between clans, so your clan membership is the key factor. Both need you to act as a team, but the logic of taking part is different. For the details of the nation war, see the BDW guide.
So if you want to take part in both the nation war and the castle siege, joining or founding a strong clan is the most sensible route.
Common mistakes in a castle siege
- Fighting alone: Players who rush in alone usually get lost in the crowd.
- Changing the target: Switching targets without telling the clan breaks the plan.
- Spreading out around the castle: A scattered clan loses the pressure it has built.
- Leaving preparation to the last minute: Potions and items checked at the last second are often missing something.
Leadership and communication in your clan
A clear leader shapes the direction of a siege. The leader's job is not to shout orders all the time but to set a clear goal and keep everyone informed. Short messages, one agreed target and a named person for each role make a big difference. If the plan changes, the leader should announce it quickly, and members should follow the new plan.
After the siege
Whether your clan takes the castle or not, a review afterwards is valuable. Talk about what went well, what broke down and what to change next time. Clans that review their sieges improve quickly, and this is one of the most useful habits you can build.
Joining a siege as a newcomer
If you are new to your clan, ask a veteran member to explain the plan before the siege starts. Stay near them, listen to their calls and learn the layout of the castle during a quiet moment. Asking questions before the battle is far better than guessing during it.
