Efficient Grinding Tips
Early Game (0-8 Fear)
Focus on eating Common Devil Flesh from any devil kills. Complete missions for bonus Fear XP.
Mid Game (8-25 Fear)
Hunt for Uncommon Devil Flesh (3.5x efficiency). Use Grip executions when possible.
Late Game (25-30 Fear)
Prioritize World Events for best loot. Only 5 more Fear needed for ultimate!
Pro Tip
Intercepting other players' missions gives both Fear XP and chance at Fiend Reroll from loot boxes.
