This guide will tell you where to farm for Morphic Transformer and Automatic Trigger in Warframe. You have to follow the simple steps in this guide to farm it.
Automatic Trigger and Morphic transformers can drop as a completion reward for completing archwing exterminate missions.
The completion rewards have a chance at giving you a mod, so each time you complete the mission, there might be times when you don’t get any mods at all. Also, automatic triggers have the higher drop chance out of the rewards you can get in the reward pool, and the morphic transformer has the lower drop chance.
So you will need to spend more time trying to get a morphic transformer than you are if you’re trying to get an automatic trigger.
