I just reached lv53 with my Fl4k and completing whatever missions I didn’t do in Mayhem 1, to get lv53 mission rewards.
After completing the Just Desserts mission. My Chocolate Thunder grenade mod came with the annointed effect: On action skill start. Regenerate 1 grenade.
It got me thinking. Would my rewards come with better annointed effects if I played on Mayhem 2 or 3? Or is it all RNG?
