Looking to grab the 10th anniversary armour set in Destiny 2? To do so you'll need to find each Cayde Stash hidden in the Old Tower area of The Pale Heart destination, each of which gives you a new piece. Once done, you'll be able to collect an ornament set of the armour pieces that you can use to transmog.
The good news is you also only have to find these chests once if you have multiple classes. Say you grab them on hunter? You'll then be able to collect the ornament sets for warlock and titan when you log in with them.
