Solving each mystery in Destiny 2's new The Edge of Fate expansion is a great way to get Tier 2 gear, as it's guaranteed to drop from each chest you open. The only caveat is that you'll need upgrades acquired on Kepler to open these ability chests. If you don't have said upgrade, you'll get a little message prompt, but each one has a symbol at the end of it that matches one of the Kepler abilities in the triumphs menu.
Each mystery will also show up on your map when you've acquired its relevant upgrade, so you can return there later and crack it open for better armour and guns. There are four Kepler abilities altogether, each of which have varying upgrade levels. Here I'll explain how to get them all and open their relevant chests.
