You buy an exotic bounty engram from xur, then you need to decode it with Petra venj and hopefully get the right quest. You then must defeat dinklebot in a match of PoE. After that you must retrieve Atheons glass dildo. Once you have the dildo you must shove it up master rahools arsehole. The last thing you must do is get 50 heavy weapon kills in trials with the fate of all fools.
