Split Chamber

[MageMeat]

Do you recommend any places, or do I just farm high level Corpus defense for it?

Got mine from Void, was beeing lucky like 2 Weeks ago and got 2 in one Void Mission... mhh was T3 Capture if im not wrong, could also have been T3 Mobile Defense.

It says tier 3 corpus.

Honestly I've had these things drop from the void and at Kiste Ceres as well, but those are RNG drops rather than defense rewards.

Good luck at finding them Tenno.

I spammed following locations til i got one:

 

Pluto - Narcissus and Outer Terminus

 

VOIDDDDD!!! Lots and lots of void.

 

And randomly from everywhere, dropped by random enemies.

Yup. Doing Corpus defense, and I have lots and lots of Void Keys to spend anyways.

I found all of my 4 Split chambers in Kiste and Kappa. Have Fun! :D

5 Splitchamber, 2 Barrel diffusion - all on Kappa(Sedna)

[Lazer]

6 Hells Chambers over the course of 34k Grineer kills at Kappa. Haven't gotten a Barrel Diffusion or Split Chamber from it yet. All my Barrel Diffusion's have been from Xini. Only 1 Split Chamber, don't remember where from. 

 

Up to you if you want to try Kappa/Kiste for it or stick with Corpus/Void. 

 

Personally I'd stick with Corpus/Void.
