Rarest Item by Drop Chance [PC]

[dziellsGamer]

So i was watching a stream and a question came up.

"by statistics what is the rarest thing to drop (warframe, weapons, ect)"

I play on PC i think i may know the Solution, but i wanted to ask the community because there may be an item rarer then what I'm thinking

Also if u post the Percentage for it to drop in your comment that would be cool

Omni Ammo Box has a 0.09% drop chance in all capture missions. I guess that's the rarest item. (excluding Primed Chamber)

Excalibur Prime.

I have no clue if I'm even allowed to post this on the forums, so apologies if I'm not. But after a quick google, here's: https://n8k6e2y6.ssl.hwcdn.net/repos/hnfvc0o3jnfvc873njb03enrf56.html

That is DEs official drop chance website. It does look sketchy but it is DE's. The accuracy of it can be questionable though since it is updated manually to avoid spoiler content.

Well If we're taking into account spawn chance and drop chance then Stalker with the Scimitar Engines at 2% is pretty damn rare

IDK if that counts since its not even a drop

By itself I'd assume the Legendary Core from sorties.

 

(By "by itself" I mean not factoring in items with a low chance that come from something that has a low chance to spawn)
