Where do you get the Frost Systems?

[Broku]

I'm one part away from making a Frost Frame, all I'm missing is the Frost Systems. I looked up a guide on where to get it and the one I found says to kill Lt. Lech Kril again and again until it's finally dropped. problem is... I've done the mission 15 times now and have gotten nothing but Excalibur pieces. Excalibur pieces ONLY. I have yet to NOT get a Excalibur drop.

So I wanted to ask for help. do I just keep fighting Kril until I get a different drop? is there a certain WarFrame I should be playing as? (I'm playing as a custom made Excalibur right now, the reason I don't want the parts for it because I already have this Frame) or does the Frost Systems drop in a different mission on another planet?

Any help will be appreciated. thanks. :)

Frost parts drop from the Vor & Lech Kril boss on Ceres, that guide is outdated
