Don't know if theres a thread on this already and I know salvage V2 is on the way.

But I've done about 6 Bhaflau Remnants runs in a row and have yet to see ANY
Skirmish Pephredos at all. Yet we saw 8 Perytons the same run. Is it still completely
random? Or are there certain conditions to be met to increase the spawn rates of each NM?

I know the Dev team doesnt really like to give out tips such as this, but they have revealed some things recently. Such as (the murasamemaru hidden effect.)
