Plan your next Book of Demons session

Our independent guide expands on the documented features of Book of Demons, offering observations that help players align their play style with the game's design without promising hidden rewards.

01 / THE GUIDE

Session Planning

Compare short versus long Flexiscope sessions by noting how many cards you can test in each. Record which session length yields the most successful runs for your current deck.

  • Try a brief session to test new card combos before committing to a longer run.
  • Observe the predicted time to gauge whether a planned session fits your available play window.

02 / THE GUIDE

Card Upgrade Strategy

List your most frequently used cards and the runes you have. Evaluate which rune combinations improve success against specific monster traits, then prioritize those upgrades.

  • Upgrade frequently used cards with runes to improve reliability in tight encounters.
  • Keep an eye on card variants that may offer situational bonuses against specific monster traits.

03 / THE GUIDE

Roguelike Preparation

Before entering Roguelike mode, run a standard campaign session and note healing usage patterns. Use that data to plan resource conservation for the harsher permadeath environment.

  • Treat early encounters as practice for the harsher constraints of roguelike runs.
  • Conserve healing items early to avoid being forced into a fatal situation later.

04 / THE GUIDE

Leaderboard Analysis

Track your monthly leaderboard rank alongside session lengths. Observe whether longer sessions correlate with higher scores, helping you decide optimal play windows.

  • Review achievement lists to identify optional challenges you might enjoy.
  • Use leaderboard rankings to gauge how your session lengths affect overall performance.

05 / THE GUIDE

Controller Comfort Test

Switch between supported controllers during identical dungeons. Note any differences in card selection speed or comfort, then choose the device that best supports the timing demands.

  • Test both Xbox and DualSense controllers to see which button layout feels more natural for card selection.
  • If playing on a TV, ensure remote play latency is low for precise timing in combat.
