Rarest Uncommon Mods

[(PSN)xPaizenx]

I'm going about the task of collecting all the mods in the game. We all know about the Corrupted and Nightmare mods and I have most, but I was wondering what are the rarest Uncommon mods to find? I know Fever Strike is one I've had trouble finding, can you guys list the rarest?

[Drathin]

I have yet to get one either :/

[Angius]

Dunno... Jagged Edge? Charged Chamber?

[Stefanovich]

Good luck getting Primed Chamber.

Contagious Spread took me 3 months to finally get. And now I need to find another one for my Sweeper. >:(

 

Pretty much all the poison damage mods are hard to get except Infected Clip.

Uncommons? Contagious spread and Fever Strike probably.

 

Rare- whirlwind, JUST whirlwind.

Whirlwind? really, i pick up at least two of these on every void run, i don't even use the glaive.

Rarest is Fever Strike I think. I never seen Primed Chamber, but I do have 2 Charged CHambers. Pm me on PS4 if you wanna buy it.

[Mistyclown]

I have one fever strike

[(PSN)xPaizenx]

Charged Chamber?? Wow, I had no idea. I swear to God I have seven right now.....

[Darzk]

Fever Strike only drops on Phobos, so thats why its pretty damn rare. Everyone hates that dustball >.>

Contagious Spread is from Electric Crawlers and Troll Drones, and they dont spawn that often.

 

Of course, the aura mods are all uncommon and can only be obtained through alerts.

 

Some other less common uncommmons (lol) are Acrobat (Rail Moas only), any of the resistance/+status mods (people sell/fuse them), Maglev (Corrupted Ancients only).

 

Gunslinger can actually be a pain, think it only drops from Napalms.

 

Spare Parts for the Sentinel can sometimes be a challenge, but drops in void and survival so not too bad.

Serration

charged chamber was a bit easier.

but tactical pump is pretty rare and pathogen rounds. 

expect pathogen rounds have a slightly better chance of getting.
