Destiny Mode is a stage in Paladog that appears as a green button on the stage select screen. In these stages, Paladog is unable to move as enemy hordes advance. The player must use units and maces that appear at the bottom of the screen to keep them at bay. The order in which maces and units come out are completely random. At the top of the screen, you will see skulls distributed evenly across the progress bar, signifying huge waves.
The upgrades of the units WILL count, although almost no ring will help you here, so just swap in some exp/gold/itemfind rings.
