If it is not at 0, the poison cloud will stay up, and any enemy that finds themselves inside it will get inflicted with decay, a new status effect that inflicts damage until the person hits 1 hp. It can be activated multiple times in a round based on the amount of fuel is in Viper’s fuel stores.
This ability allows Viper to throw an activatable smoke bomb that can be picked up and redeployed once in a round. If an enemy is in the poison they will be inflicted with damage and slowness. It also has a similar trajectory pattern to Brimstone’s Molotov ability. Viper’s C ability Snake Bite is an area of effect (AoE) type ability where she equips a chemical launcher and fires a poison canister that shatters on the ground where aimed. Before looking at her recent buffs, let's look at her abilities with a little more detail to see what they all do and how to use them. If you are unfamiliar with Viper, she uses poison to create toxic walls, smokes, and molotovs to deal with her enemies.
One agent, Viper has received many buffs which has increased her stock as a viable agent in the game. There have been a few updates to Valorant since its initial release in June.
