Void

Void portal after Regret battle

The Void is the secret final area of the game found by completing the Royal Crown quest line. This area has no definite end. you can gain no more soul in this area (even with Scythe of Libra)

Fight through hordes of monsters and sacrifice your items one by one to gain soul coins and materials from giant soul crystals that appear every 5th level in this area.

In the Void, with every 5th wave enemies become increasingly tougher by increasing bullets shot, enemy speed, and bullet speed.

You retain all the damage and heart you gained from pickups and focusing through your run, but lose stats when sacrificing relics
