Destiny 2: Darkness in the Light side quest is an exotic side quest first obtained by talking to the Drifter in the Tower after unlocking the Gambit and completing the prologue missions of the game. The quest rewards you with the exotic weapon Malfeasance, an exotic hand cannon that is considered one of the best hand cannons in the game. The gun may not be for everyone but will be a fine addition to the collection. The quest is relatively easy to get but is challenging to solve. Finishing the quest will grant you a powerful hand cannon.
