Echoing Tower 1 Best Characters

Main DPS	Calcharo Xiangli Yao
Sub-DPS	Mortefi Yinlin Lumi
Support	Baizhi Verina Shorekeeper

Best Team Composition

Main DPS	Sub-DPS	Support
Xiangli Yao	Yinlin	Shorekeeper

For this entire tower, it is best to use an Electro DPS as your primary damage dealing character. The interference benefits a character that uses Resonance Skill repeatedly and scales-off Resonance Liberation. The best team is a Xiangli Yao team supported by a Yinlin

If you do not have the best team noted above, you can replace Xiangli Yao with a Calcharo and if you also do not have Yinlin, a Mortefi.

As usual, Shorekeeper is the best support to bring for this tower, but if you don't have her or her Vigor is out a Verina or a Baizhi would work too!

Main DPS	Calcharo Xiangli Yao
Sub-DPS	Mortefi Yinlin Lumi
Support	Baizhi Verina Shorekeeper

Best Team Composition

Main DPS	Sub-DPS	Support
Xiangli Yao	Yinlin	Shorekeeper

The Electro DMG team continues to shine for this floor. If you don't have a Electro team, just don't use teams with a DPS that will be at a disadvantage with the RES of the enemies.

You can continue to use the team that you've used for the first floor whether it's a Xiangli Yao or Calcharo driven team. They would still work for this floor as effectively as the first.

Hazard Zone Echoing Tower Floor 3

Echoing Tower 3 Details

Interference
Resonators gain 30% Electro DMG Bonus. When Resonators cast Resonance Skill, their ATK is increased by 10%, and they gain 20% Resonance Liberation DMG Bonus for 4s, stacking up to 2 times. The effect's duration resets with each new stack.
Objectives
Clear the challenge Clear the challenge with at least 120s left Clear the challenge with at least 180s left

Main DPS	Calcharo Xiangli Yao
Sub-DPS	Mortefi Yinlin Lumi
Support	Baizhi Verina Shorekeeper

Best Team Composition

Main DPS	Sub-DPS	Support
Xiangli Yao	Yinlin	Shorekeeper

Similar to the first two floors, an Electro DMG team continues to be the best team to use. If you don't have a Fusion team, just avoid using a Spectro Team because the lone Lightcrusher in this floor is resistant to it.

Hazard Zone Echoing Tower Floor 4

Echoing Tower 4 Details

Interference
Resonators gain 30% Electro DMG Bonus. When Resonators cast Resonance Skill, their ATK is increased by 10%, and they gain 20% Resonance Liberation DMG Bonus for 4s, stacking up to 2 times. The effect's duration resets with each new stack.
Objectives

Enemies (Lv. 90)	Crownless
Enemy RES	Havoc
Vigor Cost	4 Vigor

Echoing Tower 4 Best Characters

Main DPS	Calcharo Xiangli Yao
Sub-DPS	Mortefi Yinlin Lumi
Support	Baizhi Verina Shorekeeper

Best Team Composition

Main DPS	Sub-DPS	Support
Xiangli Yao	Yinlin	Shorekeeper

Finally, the final floor will pit you against a Crownless that will have a lot of quick moves and speedy maneuvers. However, it will also have a lot of parry opportunities so make sure to hit them all to drain its vibration strength quickly.

For the first half of his HP, Crownless will focus on using punches and kicks so try to counterattack everytime he does. Once its HP reaches half, it will fly up and use a spear. At this time, it will focus on using sweeping and swooping attacks that are capable of dealing insane damage. Make sure to evade as much as you can!

The Electro Team will still be the best for this floor, but if you do not have one just avoid using a Havoc Team since the Crownless is resistant to it.
