Craft the pulse with the leaves on it from Riven, solar one. Make it have heal clip+ incandescent. Use it while playing Onslaught for a while or any activity. You’ll get a bunch of lunas with either or both afterwards. Don’t wanna believe me? Fine. But at least try it. Ive been gettint BRAVE rolls with the perks i have in my vault on other guns mostly. Up to you to try it out. Other option is the Crotas End AR Goodluck guardian. And don’t try to argue with me on this, it is just a friendly tip you can try or not try, the choice is all yours :)
