This guide will let you know where to get Target Cracker and Ravage in Warframe. You have to follow the simple steps in this guide to get them.
Target Cracker and ravage can drop as B rotation rewards from dark sector defense missions you can find on any planet. To get the B rotation rewards, you will need to reach round 15, then extract and repeat.
It is recommended to bring frames that can either clear the map quickly or defense frames, saryn, frost, gara, khora, octavia, etc.
The mods don’t have that low of a drop chance, so it shouldn’t take you too many runs to get the mods.
