This guide will let you know to get the Blind Justice in Warframe.
Blind Justice can drop from two main sources, On being a reward from beating Rathuum on Yam or Vodyanoi. Though it has a relatively low drop chance, so it’s likely going to take you some time before getting it.
The other way you can get the Blind Justice is by killing stalkers with about a 30% chance to drop from them. It also doesn’t matter which stalker as it can drop from the shadow stalker and the normal one you can get to spawn by either using a stalker beacon or killing a boss until the stalker starts to hunt you.
It’s likely going to take you a few times, depending on your luck, until you get the Blind Justice.
