Tome of Mastery is a unique item that allows the hero to choose a subclass for their class, unlocking additional abilities and specialization options.

• Subclass Selection: Allows choosing between different subclass options when found
• One-time Use: Each class can only select a subclass once
• Special Reward: Often found as a boss drop or special reward

• Tengu: Drops a Tome of Mastery if the player has not yet acquired one and is not a Necromancer or Gnoll
• Special Quests: May be found as rewards for completing special challenges
• Hidden Locations: Sometimes found in secret areas of the dungeon

Each class has specific subclass options:

• Warrior: Gladiator or Berserker
• Mage: Battle Mage or Warlock
• Rogue: Freerunner or Assassin
• Huntress: Sniper or Warden
• Elf: Scout or Shaman
• Necromancer: Lich (only subclass)
• Gnoll: Guardian or Witch Doctor

• Timing: Consider waiting until later in the game to use it when subclass benefits are more impactful
• Class Synergy: Choose subclasses that complement your current equipment and strategy
• Flexibility: In some game versions, you may want to save it for a different character
