Ether Daggers

[One_and_only]

Hi everyone. 
The Ether Daggers can be obtainable from a quest in warframe. But unfortunately a year ago or maybe more than a year, i sold the blueprint 
without knowing how Mastery Rank works. Today i am Mastery 22 and in my profile ( melee ) i'll be missing the Ether Daggers only.
Is there any way of purchasing it in the market or redoing the main quest again to be able to get the blueprint ?
Cause as a low mastery rank, i did not know it was a one time blueprint. Please help.

This isn't a bug report, next time if you have a question just post it in https://forums.warframe.com/forum/38-players-helping-players/ .

 

If you haven't fully ranked your either daggers, for example like you only got them to rank 6, you can request support to give you the item back!

Be sure to actually have a free slot BEFORE you open a ticket and keep it open until you get the daggers back!
