Raising Power Past the Soft Cap
Once you reach the Soft Cap, you’ll want to (and need to) start doing activities that reward powerful engrams. There is an order to it though, don’t just do anything.
You’ll, ideally, want to do activities that reward tier 1 first, and then work your way up to tier 3 rewards to get to power caps faster. This is because the tier 3 rewards offer you bigger jumps in power that you’ll want to save until last. So in other words, start with stuff like Gambit, Crucible, and Strikes and then collect your Clan Rewards and then wrap up with the tier 3s like Nightfall.
After you’ve done all of your powerful engram activities for the week, then you’re allowed to dip into your pinnacle reward activities. Pinnacles are the only rewards that can break 1550 Hard Cap and push you into Pinnacle Cap territory which ends at 1560 (the hard, hard cap for Season of the Risen).
