Fight Boss

The Fight Boss Menu

Fight Boss, also known as Boss Fights, is one of the two core features in NGU Idle that players use to unlock new content, alongside Adventure. The feature uses your Attack and Defense stats to fight against Bosses, with each consecutive boss being stronger than the previous. There are 301 bosses in total. The player's health stat in this mode is determined by (Attack * 10), and the player's health regen stat in this mode is determined by (Defense/20). Each boss defeated (except Bosses 1, 2, 4, 5, and 6), will reward the player with EXP, and certain bosses will also unlock new features and Adventure zones.

Fight Boss progress is reset upon rebirthing, meaning features and adventure zones will need to be unlocked in each rebirth.

The nuke button allows you to instantly skip past bosses you are significantly stronger than (about 1000x).

Each Difficulty has different adventure zone unlocks from Fight Boss, however the boss required to unlock each feature is independent from difficulty. Each difficulty also has the names, portraits, and lore for more bosses than the previous difficulty. Normal mode has it for bosses 1-150, Evil mode has it for bosses 1-200, and Sadistic mode has it for bosses 1-301. A full list of bosses with their stats, portraits, lore, rewards, and unlocks can be found at Boss List.

The following tables show what each boss unlocks.
