In this guide, you will come to know where to farm for Shred and Rending Strike in Warframe. Go through the guide, and follow steps carefully to farm them.
Rending Strike and Shred can drop as a completion reward for completing Tier 2 Nightmare missions found on certain planets.
The specific planets you’re going to be running nightmare missions on are Phobos, Ceres, Deimos, Jupiter, Saturn, and Europa, for the most part.
If you are doing a rescue mission, you get B Rotation Rewards by completing two of the three rescue objectives: killing all the wardens, saving the hostage, and rescuing the hostage without tripping the alarms. You need to do only two of those three objectives to get B rotation rewards.
They don’t have the lowest drop rates, so it shouldn’t take you an absurd amount of time before you get either of the mods unless you get unlucky.
