Boulder Town Martial Exhibition Day 7 Teams

Form of Thunder Best Team

Best Team for Day 7
Jing Yuan Jing Yuan Arlan Arlan Bronya Bronya Huohuo Huohuo

Jing Yuan and Arlan are Day 7's Trial Characters.

Jing Yuan will be the main DPS for this stage, while Arlan will be the Sub-DPS. With the help of Day 7's buffs, Jing Yuan or Arlan can easily spam their Ultimates by inflicting Weakness Break on enemies.

Bronya's role is to provide an extra turn for one of the DPS after the enemies recover from Weakness Break. After round 1, the extra turn may help Jing Yuan or Arlan break one of the enemies' shields again before a cycle ends, allowing them to use their Ultimate again.

Huohuo's role is to heal Arlan in case he needs it since Arlan’s Skill drains his HP. Huohuo's Ultimate can also boost the team's ATK and provide some Energy. But, if you do not need a healer for Day 7, you can replace her with one of the supports below!

Alternative Characters

Using Topaz's Skill on an enemy will increase Jing Yuan's Lightning-Lord DMG, which will help finish off the enemies on the field after spamming Jing Yuan's Ultimate.
Star Rail - TingyunTingyun Support or Healer Replacement
If you think you can use more DMG and ATK for your DPS, you can add Tingyun to your team. Tingyun can provide an ATK buff for Jing Yuan or Arlan using her Skill. If needed, Tingyun's Ultimate can also help fill out their Energy quickly.
Star Rail - BailuBailu Healer Replacement
With Bailu, you can use her Basic ATK to chip off the enemies' Toughness Bar so your DPS can Weakness Break them. You will most likely not use her Skill to heal allies. Instead, just use her Ultimate for heals.

How to Clear the Exhibition Match in 5 Cycles

Constantly Weakness Break Enemies

If you follow our recommended buffs, inflicting Weakness Break on enemies is important because when a character breaks an enemy's shield, they will instantly regenerate 100% of their Max Energy. With this, you can spam their Ultimates.

It is also important for Jing Yuan or Arlan to be the ones inflicting Weakness Break on enemies since they are your damage dealers for Day 7. Additionally, their Ultimates deal extra damage due to the Thunderous Slaps effect.

Use Ultimates Immediately

Use Jing Yuan and Arlan's Ultimates immediately since you will likely be spamming it within one cycle. Whenever you use their Ultimates, make sure that you are breaking an enemy's shield after using it to trigger Frontal Palm and regain Max Energy!
