How rare are the Invader set units?

[Kole]

cause I was thinking of doing back + double set but I've never seen one from all my XH runs.

[sesiom000]

i think they are pretty rare because i never got 1 either with 250% runs...

[Konquer]

never gotten 1 either with 350%

[Raujinn]

Never seen a single invade unit drop, been running +350% on enough PDs to nearly 60% an Austere weapon.

[jooozek]

maybe they are hidden in a secret breaking location :wacko:

[TaigaUC]

I did nearly every PD up until now, usually 3-5 times each. Usually always with +250% rare drop.
Only got 1 arm and 1 rear a few weeks ago.

So.... they are pretty rare.

2 leg from 350 buy them better than wait for rng if you can
