Hem System: Credit for prior mastered warframes? in General Discussion Posted September 4, 2020 1 minute ago, Ver1dian said: Did the same and came to the realisation that the ones that need refarming by everyone, since no prime (Harrow, Nidus, Khora, Protea, Wisp...etc.) are the real pain. Everything else is just trivial and takes 1/10 of the time to farm. Don't get it twisted; I truly feel for those that have to go through Nidus and Harrow again. It's a fate I don't wish on anyone.
