This time we’re taking a look at the quest Scholarly Observations, which has you gathering two soul shredders. You’ll likely need to play a mission several times before you can gather them and turn in the quest.
Soul shredders can be found by killing and purifying blitzers.
To farm soul shredders for the quest, I played Defensive Mission – War (online lobby) which requires you to defeat the oni horde. The mission takes place in the Age of War.
That being said, any mission that features Blitzers will do. Soul Shredders are a level 1 material so they should be pretty easy to find.
