Recommended Commands for Echoes of the Deep Tides

Suitable characters

It is highly recommended to take Hydro characters to create water reactions, as thanks to the anomaly, you can significantly increase the Hydro damage of the entire team and the resistance to interruption of the main character.

You will mainly have to fight with meks and special meks, which have a resistance to all elements of 10%, so powerful damage dealers of almost any elements are suitable for their destruction. We also advise you to take heroes from Fontaine, who have the energy of pneumousia - with them you will be able to weaken these mobs.

You will also run into treasure thieves and other common mobs, which are extremely convenient to group into one point with the help of Anemo whirlwinds, so it will not be out of place to take Lynette (C1), Sucrose, Venti or Kazuha. As for the Pyro agent and Electro magician of the cicins, Hydro and Cryo heroes work well against them.

Optimal units

The table below lists a few hero builds that will make clearing a dungeon relatively easy, provided your fighters are well trained.

How to get Echoes of the Deep Tides

The essence of this dungeon is to destroy a certain number of opponents in a specified period of time (usually 5 minutes). Thus, all your efforts should be focused on dealing maximum damage to the greatest number of enemies, so you should definitely take your very best Hydro damage dealers.

If the timer runs out and you still haven't killed all the monsters, the challenge will fail, so you'll have to start from scratch. To speed up the killing of mobs, be sure to use the bonuses of the arteries of the earth. Remember that Hydro Reactions can not only increase Hydro damage itself, but also make the character less susceptible to being knocked down.

For this reason, we advise you to first cause a Hydro reaction, and then hit the enemies with a Hydro damage using water abilities.
