Castle Siege

Castle Siege — MU Online Event Guide

Castle Siege is the largest guild event on the server and the only one that awards something permanent: the castle itself, its taxes, its shop, and the Lord Mix. It runs on a 7-day cycle that never stops — registration, ranking, preparation and the siege itself each have their own slot in the week.

The numbers below — gate health, statue health, the cost in Jewels of Guardian to upgrade them, and the damage modifiers both sides fight under — are read from the live server configuration.

Upgrading the Castle

Between sieges the owning guild spends Jewels of Guardian and zen to raise the gates and the statues. Each level is bought separately and they do not carry over if the castle changes hands.

Gate health

Level	Health	Jewels of Guardian	Zen
1	2 500 000	2	1 000 000
2	3 500 000	3	1 000 000
3	5 200 000	4	1 000 000

Statue health

Level	Health	Jewels of Guardian	Zen
1	2 200 000	3	1 000 000
2	3 400 000	5	1 000 000
3	5 000 000	7	1 000 000

Defence levels

Defence is bought separately from health and costs three times the zen.

Level	Gate — jewels	Gate — zen	Statue — jewels	Statue — zen
1	2	3 000 000	3	3 000 000
2	3	3 000 000	5	3 000 000
3	4	3 000 000	7	3 000 000

Notes

The attackers hit harder, the defenders take less

Attacking guilds fight at 300% weapon damage, defenders at 200%. Against that, everyone takes only 40% of the damage an enemy would normally do, and 20% from their own allies. The castle is meant to be takeable, not a fortress.

Gates are the softest target

A Castle Gate starts at 1 900 000 health against a Guardian Statue's 1 500 000. Fully upgraded a gate reaches 5 200 000 and a statue 5 000 000. If the owning guild has not spent jewels, the gates fall first and fast.

Registration is only open for the first 2 days

Stage 1 opens registration at the very start of the cycle and stage 2 closes it on day 1 at 23:59. Everything after that is preparation — there is no late entry.

The Lord Mix is the real prize

Owning the castle unlocks one Lord Mix per day, available to guild members of rank 3 or higher. The tax income and the castle shop come with it, but the mix is what players chase.
