Tome of Infinite Wisdom in use.

The Tome of Infinite Wisdom is a Hardmode magic weapon which is dropped by Ogre mini-boss during the Old One's Army event. When fired, it auto-fires four high-velocity pages that do not pierce. Open / Activate summons a tornado which deals 175% of the weapon's base damage, can pierce enemies, travels through one-block low roofs, lasts four seconds, and will be stopped by a wall. If used while moving on a flying mount, its pages spread out.

Its best modifier is Mythical.


  • The right-click attack's whirlwind is great for clearing out plants and thorns in the Evil Biomes and Jungle. This can help with flower collection or finding Life Fruit.
  • Although it uses a lot of mana, the Tome is able to do a lot of damage in small bursts with quick projectiles, making it useful for the Hardmode Jungle's high-health enemies. It is useful even against bosses.
  • The standard attack is great for single enemies, while the tornado attack is good for multiple targets.
  • This weapon can defeat The Destroyer with ease even in Master Mode, making it a viable weapon choice, however requires at least one of the Mechanical bosses be defeated.


  • The Tome of Infinite Wisdom's right click attack resembles the Apprentice's second ability in Dungeon Defenders 2, Tornado. It also uses the same animation as both the Forbidden armor set bonus and the Sand Elemental "Sandnado" attack.
  • This weapon, Sky Dragon's Fury, another drop acquired during the Old One's Army, and the Sergeant United Shield are the only weapons in Terraria to have both a left-click attack and right-click attack.
  • "In all their infinite wisdom" is an expression that is used almost exclusively in a derogatory or sarcastic context to denote a particularly stupid decision, made by either a single person or a larger governing body. The tooltip of "Gotta wonder who stuck a tome of infinite wisdom on a stick..." is clearly a parody of this.
