Boulder Town Martial Exhibition Day 4 Teams

Form of Flow Best Team

Best Team for Day 4
Kafka	Sampo	Tingyun	Huohuo

Kafka and Sampo are Day 4's Trial Characters.

The trial characters, Kafka and Sampo, are both essential for this stage as DoTs play a huge part in clearing it within a few cycles. Tingyun is the best Support character here as she can regenerate energy and provide ATK buffs, increasing DoT in the process.

It is essential to bring an Abundance or Preservation unit as the Malefic Ape can deal a serious amount of DMG to one of your units.

Alternative Characters

Character	Merits
Asta	SPD Buffer Support Asta can easily Weakness Break the Malefic Ape and can provide SPD and ATK buffs.
Hanya	SPD Buffer Support Hanya can regenerate Skill Points and use her Ultimate to increase a character's ATK and SPD, which enhances DoT.
Pela	DEF Shred Support Pela is a Skill Point Positive unit who can just use Basic ATKs to provide SP and use her Ultimate to decrease the DEF of all enemies.
Trailblazer (Fire)	Tank and AoE Damage Trailblazer (Fire) can help the team by taunting enemies and redirecting their attacks to them. They're especially useful against the Malefic Ape.
Gepard	Tank and Aggro Gepard can protect the entire party using his shields, which can help prevent a ton of DMG from Elite enemies.
Luocha	Heal & Cleanse Luocha also doesn't Skill Points to cleanse and heal, you can focus more on using your SP with other characters.

Form of Flow Best F2P Team

Best Free-to-Play Team for Day 4
Kafka	Sampo	Asta	Natasha

Kafka and Sampo are Day 4's Trial Characters.

If you don't have other characters built, Asta and Natasha are great free-to-play alternatives for their ATK buffs and healing respectively. Asta will have the upper hand using her Skill against the Malefic Ape, who is also weak to Fire.

Alternative Characters

Character	Merits
Serval	AoE Shock DPS Serval can be used as a third DPS to deal a decent amount of AoE DMG and inflict additional Shock DoTs on enemies.

Best Buffs for Day 4

How to Clear the Exhibition Match in 6 Cycles

Implant DoTs onto Enemies

The key to clearing this stage within a few cycles is to implant as many DoTs as you can to stack up Continuous Hook Kick, which works similarly to Wind Shear.

Prioritize Defeating Enemies

After collecting the Jumping Side Kick buff, prioritize taking out the smaller enemies to regenerate a lot of energy for your characters, especially Kafka and Sampo, so they can use their Ultimates.
