星期日 最佳隊伍
Budget Free Team
Since Sunday is a universal Harmony character, you can pair him up with any of the free DPS characters. He gives them an extra turn and provides them with offensive buffs, while also restoring their Energy through his Ultimate.
Summons Team
This team composition is an example of a Summons team. Since Sunday can also Advance Forward Summons, this makes him a great support for DPS characters who rely on Summons like Aglaea or Jing Yuan. Robin provides more offensive buffs and another Advance Forward. Huohuo restores energy and heals.
Hypercarry Team
This is an example of a Hypercarry team. Since Sunday is a universal Harmony character, you can put him in with any Hypercarry DPS. He provides turn advance, buffs, and Energy restoration.
Dual DPS Team (Himeko & Jade)
Sunday can enable a double DPS team setup by giving the main DPS extra turns, buffs, and Energy, allowing them to activate their partner like Jade.
