One of the key changes that came in Abyss of Dagath was a revision to early player rewards. When completing junctions in Warframe in the beginning planets, players would be rewarded with “Flawed” mods. These would cost less to equip on your warframes and weapons, but also give you less than their non-flawed counterparts. When the update went live it removed flawed mods from junction rewards. But in a bit of fan-service for those who would like to still have these mods, and acquire ones they missed. They were added back into the game and are now available to buy, here is the location if you would like to collect them!
Flawed Mods Bin Location in Warframe
For starters, go to Iron Wake in Warframe.
Once you land, you will want to exit the area you land in and take a left heading to the Steel Meridian vendor. Right next to the vendor will be a dumpster bin containing the flawed mods.
You will find every flawed mod in this bin, and to acquire them all you need around two million credits. But this is the location for the flawed mods, they are not very useful. However, they make a nice addition to your collection to look back on in Warframe. Credit to Game Designer Pablo for announcing and revealing the location.
