Echoing Tower 1 Best Characters

Main DPS	Lingyang Sanhua Carlotta
Sub-DPS	Taoqi Yinlin Changli Zhezhi Youhu
Support	Baizhi Verina Shorekeeper

Single Character Composition

Suggested Characters	Rover (Havoc)	Sanhua

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.

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

With the Glacio RES decrease present in the interference, we suggest using the free character Sanhua as the DPS that will clear two first two floors. Of course, we still suggest stronger Glacio characters like Carlotta but they are better reserved for later floors with harder enemies. You can also use Rover-Havoc as the other free-to-play option. Just know that they won't have the buff from the interference.

Support	Baizhi Verina Shorekeeper

Single Character Composition

Suggested Characters	Rover (Havoc)	Sanhua

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.

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

With the Spectro RES decrease present in the interference, we suggest using the free character Sanhua as the DPS that will clear two first two floors. Of course, we still suggest stronger Spectro characters like Jinhsi but they are better reserved for later floors with harder enemies. You can also use Havoc-Rover if you have them built over the Spectro version. Just know that they won't have the buff from the interference.

Hazard Zone Echoing Tower Floor 3

Echoing Tower 3 Details

Interference
Enemy Glacio RES descreases by 10% When Resonators cast Resonance Liberation, their ATK is increased by 5%, and they gain 10% Resonance Skill DMG Bonus for 3s, stacking up to 4 times. The effect will be removed when the active Resonator is switched off the field.

Enemies (Lv. 80)	Diurnus Knight
Enemy RES	Spectro
Vigor Cost	3 Vigor

Echoing Tower 3 Best Characters

Main DPS	Lingyang Sanhua Carlotta
Sub-DPS	Taoqi Yinlin Changli Zhezhi Youhu
Support	Baizhi Verina Shorekeeper

Suggested Non-Glacio Team Comps

Main DPS	Sub-DPS	Support
Camellya	Sanhua	Baizhi
Xiangli Yao	Yinlin	Baizhi

The third floor is where the difficulty can ramp up. For this floor, we suggest saving the strong Glacio team of Carlotta for the final tower. For this floor and the next, we suggest going for Non-Glacio team that is not Spectro. This way, you can still have a fighting chance with the bosses while saving the Glacio team for the final Tower.

Of course, if you want to use the full Carlotta Glacio team, you can do so as they are the best team for this tower. This is true if you have a Jiyan team, which is great in the final tower because of the Aero buffs due to the interference. Just take note that if you use Carlotta's team here, and want to use them in the final Tower they won't have enough Vigor.
