Spellbooks are a platforming challenge in Shovel Knight found primarily in Pridemoor Keep. They appear as large leather-bound books that hover in mid-air. When the player touches it with any attack, it will open and and activate hidden platforms that look like sequences of small pages. The book will deactivate after a short time (indicated by flashing) at which time it will snap shut and the small platforms will disappear until the book is opened again. If the book is struck while open it will reset the timer.
In Specter of Torment, some platforms will form walls for climbing.
