MasterMU Castle Siege Guide
Castle Siege is an alliance-based PvP battle where coordination matters as much as combat power. Attackers must control both Crown Switches while their Guild Master seals the Crown, and every objective, defensive action and elimination contributes to the alliance score.

How Castle Siege Is Won
All guilds in the same alliance fight as one team. The objective is to build the highest total score by attacking castle structures, controlling key positions and defeating opponents.
Points from Castle Structures
Points from Defense and Crown Control
PvP Elimination Points
The value of an elimination depends on the defeated player's guild role. Fighting inside the Throne Room and assigning key attacking roles can multiply that value considerably.
Multiplier rules: Eliminations inside the Throne Room award 5x points. When an attacking Battle Master or Assistant Guild Master makes the elimination, the result receives an additional 2x multiplier. These multipliers stack: an attacking Assistant defeating a member inside the Throne Room earns 10 points, while an attacking Battle Master defeating a Guild Master there earns 250 points.
Attack and Defense Damage Balance
Defenders retain full base damage, giving the castle owners a combat advantage. Attackers must compensate through alliance coordination, role selection and control of the Throne Room.
Rush Time Multipliers
The closing stage increases every point bonus, allowing a coordinated alliance to close a score gap or secure its lead.
Example: A member eliminated inside the Throne Room is normally worth 5 points. With 6 minutes remaining, the same elimination awards 10 points.
Guild Victory and Participation Rewards
Reward eligibility requires both the player and their Guild Master to spend at least 600 seconds inside the Throne Room during the event.
Reward Delivery Warning: After Castle Siege ends, remain on the same map for at least 1 full minute while the rewards are delivered. If you change maps during this waiting period, you will not receive the rewards.
Losing Guild Master requirement: To qualify for the losing reward, the Guild Master must accumulate at least one second with both switches controlled and the Crown activated during the event.
Individual Ranking Rewards
Three leaderboards reward different contributions: eliminations, total points and time controlling a Crown Switch.
