+ Sprays a toxic gas in a radius that deal damages enemies that come in contact with it.*
+ Airblasted projectiles do crit damage instead of mini crits

- can't deal crit damage at all ( not affected by Kritzkrieg nor Victory crit buff )

*
- Gas last for 20 secs
- Gas deals double damage to spies
- Enemy Pyros take 25% less damage from gas
- Enemy Pyros can airblast away gas
- If lighted by an enemy , the gas will cause an explosion , damaging all nearby teamates by 50 damage

+Spray toxic gas that deals damage overtime
+Air blast turned into toxic cloud which will last 2 seconds before dissapearing
+When the toxic cloud is lighted by fire, it will explode in a small area, causing damage
+Poisoned players would have a 10% speed penalty
-Toxic cloud can be airblasted away by enemy pyros
-30% damage penalty
-50% afterburn damage

Update stat:
No random crits, this weapon cannot crit nor mini crit

Makes enemies drugged on hit for 3 seconds
-10% damage
-50% ammo capacity
+20% weapon switch time (takes longer to switch)

The stats the creator made are perfect. The only thing that I think would make it better is, you can be damaged by the lingering gas clouds
