The requirements for upgrading a guild:

When a guild meets the above requirements, the Guild Leader can upgrade the guild at the Manager in Guild HQ.
Guild consumption:
Guild contribution, guild funds and guild construction are consumed from Monday to Friday of every week. Below are the related formulas:
1. Guild contribution deducted = Max (Own contribution/500*guild level, guild level*100). If there is not enough Guild Contribution, the player will not gain Statue bonuses.
2. Guild fund deducted = Guild level*100*the number of guild members. If the guild doesn't have enough guild funds, only the Guild Construction is deducted, but the players in the guild will not gain Statue bonuses.
3. Guild construction = Guild level*the number of guild members*0.05 guild level*2. If the guild doesn't have enough Guild Construction, the guild will be disbanded but the system will inform Guild members five days ahead.

Disbanding a guild

Condition to disband 1: At 06:00am, if a guild doesn't have enough Guild Construction to maintain it, it will be disbanded. For example, a level 5 guild will be disbanded if it has less than 90,000 Guild Construction at 06:00am and a Level 3 guild will be disbanded if it has less than 10,000 Guild Construction.
Condition to disband 2: At 06:00am, if a guild has less than 10 members, it will be disbanded at once.
Condition to disband 3: If a guild doesn't have enough guild funds and it cannot afford the guild's consumption for two days successively, it will be disbanded.
