addedNew Starting Decks and "Accumulate"Each character now has a new starting deck unlocking at Mastery Level 7 that features the new Accumulate mechanic.

addedNew Starting Decks and "Accumulate"Accumulate adds a special card called Singularity to your hand (if you don't already have one), then infuses Singularity with keywords or runes, letting you stack up several bonuses onto one card. You can use these bonuses as you get them, or build up a huge attack and unleash it all at once!

addedNew Starting Decks and "Accumulate"There are 30+ new cards that use the Accumulate mechanic (or the inverted Decumulate, which lets you tap into Singularity to fuel other effects). These new cards don't normally appear in rewards - you have to start a run with one of the new starting decks to see them! Keep an eye out for cards with a shifting purple card frame, since they will interact with your Accumulate cards.
