Destiny 2 server maintenance is complete, the 1.1.0 update is live, and the Curse of Osiris expansion is now available to play. With all of that comes patch notes, which detail a host of changes to weapons, armor, classes, activities, and even the mobile companion app. Let's have a look!

Arc Titans will notice right off the hop that the advantage they've enjoyed over their fellow heavy-hitters has been dialed back somewhat: Pulse grenade damage has been "slightly" reduced, as has the camera shake effect they inflict on players caught in their blast. The recharge rate of second grenades has also been slowed, so you won't be able to toss them out quite so quickly anymore. The recharge rate of Arcbolt grenades, and also Firebolt, have been "normalized" to match the other grenade types.
