Spell book
From The Heroes of Might and Magic III wiki
(Redirected from Spell Book)
Spell book is an object where heroes store their learned spells. It is also needed to cast a spell. Any hero can have a spell book, but typically might heroes (e.g. Knights or Beastmasters) do not have them at the beginning of custom scenarios; however, Alchemists and Death Knights do both start with a spell book. Spell books can be bought from a mage guild for 500 or obtained by equipping Titan's Thunder combination artifact. A spell book cannot be traded to another hero, nor can it be lost after a defeat.
