A spellbook that has gone too long without being read. It overflows with magic, forming thick armour from its binding, legs from its pages, and periodically erupting in flurries of free-floating, self-casting spells.

It is encrusted with long, sharp, deadly-looking crystals.

Useful Info

Walking crystal tomes conjure living Lehudib's Crystal Spears. While they make melee attacks at half speed, they cast living spells at the normal rate. Walking tomes are most often seen in the Depths and the wizlab, Tukima's Studio.

Tips & Tricks

  • If you don't have any sort of AOE, crystal tomes are impeccably scary in an open area. They can deal up to 306 damage per turn, enough to one-shot most characters, period. While the chance of actually taking 306 damage is minuscule (each crystal spear can miss, be blocked, or be reduced by AC), the damage output can still be very, very high.
  • Living spells work similarly to the player Foxfire spell. It creates a living spell entity, which must have a direct path to a hostile target. If you are in melee range with a tome in a corridor, most of the living spells will be unable to hit you. But unlike the foxfire spell, living spells can spawn behind the player (radius-2 of the walking tome), so a corridor is not foolproof.
    • You can attack a living spell, which will destroy it before it gets the chance to cast itself. Most types of AOE attacks can destroy a few spells while damaging the tome in the process.
  • Silence works on walking tomes, preventing them from casting at all.


  • In 0.31, walking crystal tomes will only create 1-2 living spells per cast.
  • Prior to 0.30, walking tomes' spells weren't silenceable.
  • Prior to 0.29, walking crystal tomes had 20 HD, so they dealt 3d40 damage per crystal spear.
  • Walking crystal tomes were added in 0.28.
