How to Play Viessa in The First Descendant
In Nexon‘s shooter, Viessa starts out as a crowd-control Descendant. However, once you slot in the Hypothermy Module, her CC is replaced by DoT, and her DPS gets a significant boost.
This lets her have amazing AoE as well as single-target clear speed making her one of the most versatile characters in The First Descendant. However, getting Viessa’s best build done can take a fair bit of time and grind.
You will need to invest in the endgame content loop, but once you have her made, she will be able to breeze through most content in the shooter.
Here are some of Viessa’s pros and cons if you are looking to main her in The First Descendant:
Pros:
- Has amazing single-target burst damage
- CC can be replaced with DoT to maximize her DPS potential
- One of the easier Descendants to pick up
- Has a very versatile playstyle
Cons:
- Lacks any mobility tools making it hard for her to reposition.
- Get the DoT effect only after gaining the Hypothermy Module in endgame
