Each week in Destiny 2’s Season of Opulence, Werner 99-40, one of the Tower robots hacked by Cabal Emperor Calus, gives you four bounties that can help you completely upgrade your Chalice of Opulence. Those bounties have the usual requirements–get a certain number of kills, for instance, or complete a certain type of activity. But completing that step of each bounty only earns you a Treasure Map, and it’s up to you to follow it to find the Runes, Imperials, and legendary drops the bounties promise.While the bounties themselves are often a bit time-consuming to complete, the glowing treasure chests they drop are also usually a bit tough to find. Calus loves to leave them in out-of-the-way places that aren’t always immediately obvious. Luckily, we’ve tracked down each of Calus’s treasures to show you exactly where to go to snag them.The Salvaged Goods bounty requires you to pick up five Legendary engrams from drops in any activity, which means if you just play the game as normal, you’ll eventually complete this bounty without any extra effort. Clearing it earns you the map, which sends you to Io.Where To Find The TreasureOn Io, you’re looking for the Spine Burrows area. It looks like the location you want is near Giant’s Scar, but in fact, it’s accessible from Lost Oasis. Pick the Lost Oasis landing zone, then hop on your sparrow and head due east toward the edge of the area (toward where “Spine Burrows” is marked on the map). When you arrive, you should see a cave opening with a stream of blue water leading into it–that’s where you’re headed.Follow the cave tunnel until you hit a large room filled with Taken. The Spine Burrows name should come up on your screen to let you know you’re in the right place. The chest you want is on the ground on your right; hop across to the small ledge in front of you on your right side and follow the tunnel through.You’ll exit next to a big tree. Drop down to the ground below and do a 180 and you should find the chest right behind you.
