"The spellbook for Incendio is behind this door, but so is the Vaults Guardian. If you want to unlock the door, you'll need five gemstones to create a special key. I cannot help you find them."
—A Gringotts goblin[src]

The Incendio spellbook is a book with instructions and information on the Fire-Making Spell, owned by Filius Flitwick, Pomona Sprout and the goblins of Gringotts Wizarding Bank.

During his first year at Hogwarts School of Witchcraft and Wizardry Harry found the spellbook, during a challenge created by Professors Filius Flitwick and Pomona Sprout. During his second year, Harry did another challenge created by Flitwick, to find the spellbook. A copy of the spellbook was stored in one of the vaults at Gringotts Wizarding Bank, guarded by the Vaults Guardian, a giant Fire Crab. Harry had to collect five gemstones to create a key to get into the vault and collect the spellbook.

Behind the scenes

  • Flitwick created both challenges in the console versions of both games.
  • Sprout created the first challenge in the PC version.
  • Only in the GBA version that spellbook was kept in a vault at Gringotts.
