Tower Defense - Recommended Characters

Characters That Can Delay Movements & Crowd Control

Characters Can Delay Movements

Most of the opponents are easily controlled and caused to float. However, there are also enemies that cannot be easily controlled, so make sure to leave a spot in your team for those particularly huge enemies.

Send Enemies To Holes

Another way of defeating enemies is to blast them into holes, thereby defeating them. This is very effective against small enemies.

Earth Structures Can Block Enemies & Delay Them

You can delay the enemies using geo structures produced by Zhongli & Traveler (Geo). Use these to delay huge enemies.

Hydro & Cryo To Freeze Enemies

Huge Monsters Can Be Stopped By Freezing

Ruin Guards, Lawachurls and other large opponents can be delayed by freezing them. Performing an elemental combo with Hydro / Cryo Mechanicus is also recommended.

Shield Destroying Characters

There are a lot of enemies that you will face who have elemental shields. We also strongly recommend you bring characters that can destroy shields on your team!
