While some of the most significant challenges in Destiny 2 come in the form of Grandmaster Nightfall strikes or the Trials of Osiris PvP mode, veteran players know the true endgame is looking cool. There is no shortage of ways for players to customize their Guardians in Destiny 2, from different ships and armor shaders to the animation shown when players load into an area. One type of cosmetic, however, requires a little more work and know-how before players will be able to show them off. Mementos allow players to display their prowess with a unique weapon appearance and customization, but players will need to put in a little effort first.
