I have been trying a lot to find them. I completed 3 invasions always helping the corpus of course. 7/5, 6/6 and 5/5 invasions missions on Phobos. I have four deadmarks from Vay Hek and only saw them once. Got the Brakk blueprint and no element for its founding. Any tips on how to provoqe them? Should I keep doing invasion missions or should I try any regular missions on a Grinner planet? Sorry for my english
