Buying Weapons Over My Rank In Bundle?

[SaveurMum]

Hey guys, I am Mastery Rank 4 and I'd like to know if I could buy the Update 10 Bundle (with Nekros, Soma etc.) and use the Soma, even though it requires rank 6 to buy normally, at rank 4?

Mhm i don't think you can use the soma at rank 4. Just buy some weapons and get to rank 6.

Yeah i don't think you can yet.  Or perhaps, it circumnavigates the mastery requirement because u used plat.  IDK.
