Like just about the entire playerbase, I've been looking forward to crafting Aberrant Action today. It's the first solar rocket-powered sidearm in Destiny 2 and it comes with a stacked set of perks. The gun was added to the game as part of Act 2 of Echoes, along with an arc heavy-burst pulse rife called Corrasion, at the weekly reset.
If, like me, you've saved up enough quest XP to turn in and unlock a copy of Aberrant Action from the season pass, you might be confused as to why the gun still can't be focused from Failsafe, the vendor at the H.E.L.M. social space. The answer is because you first need to progress the seasonal questline. Here's the order of business, assuming you're already up to date with the questline from episode 1, if not you'll need to finish that first.
