Guild Battle is a guild-based regular major event taken place once a week
Pre-battle: sign up
The president of guild needs to sign up for Guild Battle on behalf of his/her guild and its members, and select who to join. If the president hasn't signed up, his or her guild will be treated as a loser directly and pay 30% of their tax revenue. Guild's matched zone is decided by its tax revenue last week. Three matched zone are available: bronze, elite, and master zone.
Guild Battle will begin following 24 hours of sign-up and preparation time.
During the battle: Guild Battle is 30-minutes long each time. All participants choose their bull or cow to join the battle, attack the opponent's Taurus.
Cows only make up 20% or less of each guild team and play the role of recovering Taurus's HP.
Selected members can enter the battle unlimited times until the end of Guild Battle and dead of either side's Taurus.
The winner guild can take back its staked tax revenue and plunder the opponent's staked tax revenue.
