All main bosses have increased durability and new ultimate abilities. Battle time limits have also been extended—get ready for some all-out team fights!

The Wailing Knight has long wandered the Undead Ruins. Now, he awaits your challenge.

This boss features three phases and numerous arena-wide abilities that can reduce your maximum HP or deal true damage.

An additional hidden boss also awaits those brave enough to take on the highest difficulty!

• New card: Wall of Sighs. Allows you to banish items from the current run via the selection screen.
