Decked Out Achievement
Have Purple-rarity gear or better equipped in every slot.For this achievement you will need all four gun slots, as well as your shield, grenade, class, and relic mod slots to have an item equipped of either purple (rare), orange (legendary), or pink (seraph) rarity. The hardest one to get will likely be the relic mod, so utilize the seraph crystal shop in town for this. Every time I checked, the item of the day was a relic mod for only 50 crystals. The lootapult will also be a huge help, as it almost always give a purple item of some kind. You should also get a good amount from the chests after completing the raid.
