Ashes are a consumable resource obtained from fire-affinity enemies, scorched areas, and later rooms in Erebus. They drop reliably from standard combat and accumulate at a steady pace during normal play, with Hestia-related boons boosting yield further when Burn-afflicted enemies are defeated.

• Resetting and rearranging Arcana Card slots on the board, enabling mid-progression build experiments
• Supplementary ingredient in certain Cauldron Incantation recipes
• Exchanged alongside Bones in some upgrade menus as a secondary cost component

Ashes are most valuable to players who frequently experiment with different Arcana combinations. Once a board configuration is settled, surplus Ashes accumulate quickly. Rather than hoarding them, use them freely whenever you want to test a new layout — their relatively abundant supply makes experimentation low-cost.
