The sight of a large army is easy to understand. The preparation behind a useful army takes more work. In Law of Kings, alliance warfare begins with cities that can support their plans and players who know what they are trying to achieve together.
Use these questions to prepare a discussion with your allies. The linked wiki references explain the specific game systems.
What can your cities sustain?
Training is only one part of the cost of an army. Troops also require food upkeep, and a growing force competes with other development priorities. Review production and consumption before committing to a campaign that assumes more than your cities can support.
Read the economy and upkeep guide and compare troop costs and requirements. A plan based on your actual cities is easier for allies to rely on.
What is the objective?
A raid, a defensive commitment, and an attempt to capture a citadel ask different things of a group. Agree on the target, the reason for choosing it, and who will make the decision to proceed. If the objective changes, discuss the change before players commit their armies.
For state objectives, start with the citadel reference. A level 16 citadel is an advanced target with a garrison and fortifications that demand serious preparation.
What do you know about the target?
Old information can lead a group to plan for a battle that no longer exists. Review scouting information together, identify the parts you still do not know, and avoid treating assumptions as confirmed reports.
The scouting and combat guide is the next step. Compare it with the defenses reference and relevant troop pages before deciding on an army composition.
Who needs to hear the plan?
Write a brief shared plan with the objective, responsible players, communication channel, and the circumstances that would cause you to pause. Ask members to confirm what they can contribute. Clear expectations make it easier to spot a gap while there is still time to address it.
Explore the alliance systems, then use your own group’s communication to turn the information into a coordinated decision. A strong first siege begins with a plan everyone understands.
