Hallucinogenic Gas Grenades
Imagine if there was a grenade from the superstore that when thrown would release gas for around 10 seconds and cause all organic life, including fellow divers, to hallucinate.
For example Bile Titans would look around and spew acid in completely random directions, Chargers would run off into random paths, and regular enemies would sometimes attack each other or attack the sky.
Other divers may see Enemies as other divers while in the gas or see enemies when there are none around them.
This would not affect the Automatons because they don't need to breathe, also making it somewhat balanced as it would be highly effective in Terminids or Illuminate but not Automatons
