Jade and Herta are the trial characters for Day 7.
We recommend using a Follow-Up attack team composed of Jade, Herta, Robin, and Huohuo. Most of your damage will come from Jade and Herta's Follow-Up attacks while Robin and Huohuo provide ATK buffs and Energy.

| Support |
You can swap Robin out for an additional AoE DPS like Himeko or Jingliu to build more Starlight stacks a lot faster. Himeko's Follow-Up attacks will be especially helpful with this.
However, you can also substitute Robin with other supports like Tingyun or Ruan Mei. Then, you can go with any Abundance character as a healer replacement but Luocha's passive healing will be more Skill Point friendly.

In this F2P team, Asta can grant ATK boosts while decreasing enemy HP to help trigger Herta's Follow-Up attacks. Meanwhile, Lynx can provide healing for the team and help chip away the toughness of Quantum-weak enemies.

The Day 7 stage mechanic features the Starlight buff, which stacks and increases your team's DMG every time allies deal damage with Ultimates or Follow-Up attacks.
Every 10 Starlight stacks earned will also launch an attack on all enemies, so you should use your Ultimates and try to trigger Follow-Up attacks as much as possible!

The Abundant Ebon Deer will appear as a boss. Try to aim your characters' attacks on the Deer's summons while still keeping the boss within radius. This will help decrease their HP faster and trigger Herta's Follow-Up attacks more often.
