Echoing Tower 1 Best Characters

Main DPS	Lingyang Sanhua Carlotta
Sub-DPS	Sanhua Zhezhi Cantarella
Support	Baizhi Verina Shorekeeper

Single Character Composition

Suggested Character	Sanhua

Change to Freezing Frost for more damage if you're running Sanhua with Moonlit Clouds.

Full Team Suggestion

DPS 1	DPS 2	Support
Carlotta	Zhezhi	Shorekeeper

For the first two floors of this Tower, the enemies are quite easy to deal with using a single built character. Just make sure you are evading all attacks and using a well built character for this floor.

The best one to use for this floor is going to be Sanhua due to the Glacio RES reduction provided by the Interference in the Echoing Tower.

If you have enough characters, you can still go ahead and use the full Carlotta DPS team but using only one character can save Vigor especially for universal supports like Shorekeeper and Verina.

Like the first floor, enemies in floor two are still quite easy to deal with using a single built character. Just make sure you are evading all attacks and using a well built character for this floor. The best one to use for this floor is going to be Sanhua due to fighting Fusion enemies.

If you have enough characters, you can still go ahead and use the full Carlotta DPS team but using only one character can save Vigor especially for universal supports like Shorekeeper and Verina.

Main DPS	Lingyang Carlotta
Sub-DPS	Sanhua Zhezhi Cantarella
Support	Baizhi Verina Shorekeeper

Full Team Suggestion

DPS 1	DPS 2	Support
Carlotta	Zhezhi	Shorekeeper

As the difficulty for Floor 3 onwards is significantly higher, we recommend using a full team setup. The best team for this floor would be the Carlotta DPS Team as she gets the full benefits from the interference buffs.

Make sure to rotate through Shorekeeper and Zhezhi's kits to buff Carlotta. Provide her with stat buffs and coordinated attacks to defeat the enemies quickly.

As with the third floor, we recommend continuing to use the Carlotta DPS team to fight Inferno Rider efficiently. Avoid its attacks with Carlotta and Zhezhi's mobility, while dealing continuous damage with the team's optimal rotations.
