Update: New Starting Decks, Accumulate, and More

Moonsigil Atlas · published 29 Jul 2026, 15:09 UTC · build 24422012

All newsPlayers around this dateRead on Steam

Hello Sigilwrights!We've just launched an update featuring new starting decks and the new Accumulate mechanic, as well as a few bugfixes and quality-of-life changes!

New Starting Decks and "Accumulate"

Each character now has a new starting deck unlocking at Mastery Level 7 that features the new Accumulate mechanic.

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!

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.

We've also fixed a number of bugs and added some quality of life changes, take a look at the full patch notes below!
