Poisonburst Special Ammo for Bomb Launcher & Lance

Would be kinda cool to give these two a Poisonburst Ammo Variant which provides distinct benefits:

Cost: 250 Hunt Dollars
Ammo Count: 5+1
Unique Attributes: Deadly Poison status effect

Upon firing, if it lands on a surface it explodes a postule that covers the area around the contact point in deadly poison.

Cloud radius: 4 meters
Duration: 400 seconds
Cloud Density: Extremely Thick
Deadly Poison: Poison that saps tissue and is elevated by the Poison Immunity Status Effect. Resulting in Hunter’s inverting the benefits of the Poison Immunity Status Effect. This means that you take more damage from Poison if you have Poison Immunity. BUT if you don’t, Deadly Poison does DOT damage very similar to Bleed and can be mended (Like Bleed) easily off of Hunters.

If you directly land a shot on a Hunter, (Only Enemy Hunters) the Harpoon constantly ejects miniature Poisonbursts that follow their hosts position. The clouds don’t last long but can cause huge collateral damage if you aren’t careful. The lingering Clouds do NOT effect its’ Host

Attach Duration: 8 seconds
Damage: 125 (Body) 90 (Legs and Arms)
Cloud Radius: 1 Metre
Cloud Damage: 7 Damage/sec
Cloud Infliction: Deaf Effect and Blurry Vision to non-Hosts
Cloud Duration: 10 seconds

I know my idea is out there but tell me your thoughts! Stupid idea? Or does the idea have Potential?
