Well, what the title says. I just converted the first Kuva Lich I spawned, and since I was using Kullervo at the time and didn't know about Kuva Liches, his armor looks a lot like Kullervo's. I haven't done a Sister a Parvos yet, but I assume their appearance will reflect the warframe that stabs them a little.
My main question is this: will stabbing them with a prime warframe give them an appearance based off the prime version, or will their appearance just be from the default regular version?
