[Kuva lich chat linking?]

I totally agree. I want to show my friend what my Lich can do and how he looks like. Or add a Tab on your Profile.. would also be very nice 😄

[kuva lich can steal sortie reward]

Very cool. I like it. You are gonna hate your Lich. Then you kill it and you get a bunch of stuff back. Cool very cool.

[Nidus and Helminth]

Your Nidus will get a cyst now. So all okay 🙂 The room itself is a pretty cool one i like it a lot.

[Noob question about Prime Warframes]

You can buy them like Valklyr and Saryn as soon as they geht available. If this is the case then you can buy the Prime Access or you can farm the Relics ingame and open them to get your Prime Parts. Only 2 Warframes at the same time get unvaulted. For Frost is maybe a change planned as you can read here.

On the other Hand it is possible to buy the parts from other players with platinum. The Mesa Relics for example are still there und you can easily farm mesa.
