@SquidHunterX firstoff nice Avatar (had a similar one in the past), also yeah it is the replacement to the disruptor, but has wider coverage and is overall better.
The disruptor was good, but mainly on weapons with bubbler since people would keep close to allies to prevent attacks, plus it cost alot of ink so it left you pretty vulerable making it hard to again do anything other than mark and run away.
This posion mist will be alot better, allowing you to keep pressure off chargers, and rainmakers, due to the slow and ink loss ability, while also giving the possibly to provide some cover to confuse enemies.
P.S "What is the Super Chakchi"?
Also really loving the ouch, used to spam booyah to warn teammates of enemies, not one ever listened....
