Custom Mode

Custom Mode is an unlockable mode in Dead Cells, that allows you to adjust your runs as you see fit. This game mode is available by absorbing the Customization Rune, obtained from killing a unique Elite Zombie at the start of Ramparts, but some configurations are available only by beating the game at harder difficulties.

This mode allows you to limit your current item and mutation pool, enabling and disabling meta modifiers (such as amount of flask charges), adding starter items with varying qualities, adjusting the timer settings, et cetera. Some options prevent you from obtaining achievements. You can only use items that have been unlocked through The Collector in Custom Mode.

Custom Mode has a set of controls (shown for keyboard use) that will help navigating through the mode:
 * Q and E: Quick swap between main categories
 * Space: Confirm
 * Esc: Back
