For strategies, refer to GvG Strategy

Guild versus Guild battles are a core aspect of Unison League.

GvG battles occur three times a day at varying time tables. They consist of 5 Members on the field of battle at a time, and 5 substitutes per guild. The objective of a Guild versus Guild battle is to defeat 5 enemies to conclude the duelling round and proceed to either the "Crystal Assault" phase, or the "Guild Recovery" phase, depending on your round victory or loss respectively.

Once a Guild versus Guild battle is completed, the participants are rewarded with Proficiency Points, Friendship Points, Gold, Gems, and Grand or Legendary Medals.

If for instance, less than 5 human players were participating within a Guild battle, an AI or CPU will play your absent guild member's characters for them. You can identify humanoid players to computers by the "CPU" icon above their characters status bar.

Schedule A has matches starting at 1:00 p.m., 6:00 p.m., and 9:00 p.m, Schedule B starts at 2:00 p.m., 7:00 p.m., and 10:00 p.m, Schedule C starts at 1:00 p.m., 3:00 p.m., and 6:00 a.m., while Schedule D (which was recently added) starts at 10:00 p.m., 6:00 a.m., and 8:00 a.m.

If the guild scheduled to battle is disbanded before the match, you will still battle, but with a guild of low leveled CPU's with a low level crystal called Unison Squadron. The win is yours.
