About Book of Fei
Book of Fei is a cute, casual idle RPG that runs directly on your computer desktop. The interface sits at the bottom of the screen, letting you adventure while you work. You explore regions, battle monsters, and uncover the realm’s truth, all without leaving your desktop.
The game offers six heroes, more than 24 advanced classes, and a level cap of 2000. You can collect equipment, card gear, badges, and artifacts, then enhance them to build a powerful party that can tackle endless defense waves and high‑difficulty dungeons.

Desktop Integration
The game window appears at the bottom of your system desktop, providing companionship during busy work hours. Features like screen resizing, interface scaling, one‑click hide, and instant concealment let you keep the game unobtrusive.
A transparent window design and a system‑tray hide option let you switch between work and play instantly, while mouse‑only and touch‑only options ensure you can interact without a keyboard.
- Try the one‑click hide to keep the game out of sight when you need full screen for work.
- Adjust the interface scaling to match your monitor resolution for clearer reading.

Hero Progression & Classes
Six heroes can each awaken into ultimate classes, each with unique combat mechanics and skills. Over 24 advanced classes and a level cap of 2000 give deep progression paths.
Heroes gain experience through battle tiles for auto‑farming and can be assigned to work tiles for idle gold, allowing simultaneous leveling and resource gathering.
- Experiment with different advanced classes after each hero reaches higher levels.
- Balance battle tile runs with work tile assignments to keep gold flowing.

Equipment & Badge Enhancement
Hundreds of equipment pieces and card gear can be collected and enhanced. Equipment has quality tiers that set different enhancement caps, while badges add stat bonuses up to +100 levels.
Soul Badges form a separate line with their own progression curve and visual glow effects, offering another layer of power scaling for your squad.
- Prioritize higher‑quality equipment early to reach higher enhancement caps faster.
- Mix regular badges with Soul Badges to diversify stat bonuses.

Awakening & Endgame Systems
All six heroes can awaken into ultimate classes that play differently, unlocking new combat mechanics. After all heroes are Awakened, the Paragon talent board becomes available, offering a shared pool of talent points on a hexagonal layout.
The game also features an Endless Defense mode, a tower‑defense style wave combat, and a Forge Temple with over 20 difficulty tiers where enemies have demonic shields that must be shattered, and heroes can be sent to train and craft mythical equipment.
- Use the Paragon talent board to specialize your awakened heroes for specific wave strategies.
- In Forge Temple, focus on shattering demonic shields early to speed up material collection.

Auto Challenge & Idle Mechanics
The Auto Challenge system provides hands‑free stage progression, automatically switching between main‑story battles and work‑for‑gold phases while harvesting results. This lets you level and earn gold without active input.
Idle gold is earned through work tiles, and auto‑harvest collects battle rewards, making the game playable at your own pace without timed input.
- Enable auto‑challenge during long work sessions to keep progress moving.
- Combine auto‑challenge with work tiles to maximize gold while battles run.
