Giant worm[1] is a dangerous[2] hostile creature that appears from time to time in the deep underground of Snow and Desert Worlds.


The giant worm only appears around dwarfs, i.e. it won't mess with random deep underground areas if dwarfs aren't there.

It takes a while to reappear, i.e. not twice between raids.

With the parameters above it's possible to somewhat limit/control the worm occurrence.

Totems placed deep underground block the worms' spawning within their influence radius.


The giant worm causes earthquakes when it strikes and removes a row of ten to twenty blocks. The displaced resources fall on the ground and none of them are lost, excepting earth. The worm eats 20% of the displaced earth resources.

It causes panic in dwarfs, making them paralize or run away, ignoring any attack orders around the worm.

The worm also inflicts a low area damage while passing by dwarfs. Despite its bestiary description, it represents no danger in standard campaign difficulty levels.


Worm hunter.jpg

The Worm hunter achievement is unlocked killing a giant worm.


  1. Have a ridiculous amount of mana
  2. Use several magic explosions (not less than 8) on the worm until it has almost no health (almost invisible tiny heart Monster Health.png)
  3. Use a couple of fireballs (if step 2 is done correctly, 1 fireball is enough)
  4. Collect the loot.

Friendly tips[]

  • Do it on the central part of the map to reduce the mana costs.
  • Do it just before leveling up so you don't starve for mana after killing the worm.
  • Don't do it on very low XP levels, as your mana pool doesn't match step 1.
  • Open a portal and enter "Siege Mode" before using the spells to avoid damaging dwarfs.
  • Order an "attack" after "sieging" to tag the worm with the crossed swords icon, so you can target the spells right over the icon


The giant worm is, along with the giant spiders, the most annoying creatures in Craft the World.[3]

Besides placing Totems everywhere underground to avoid worms, annoyed players can follow the instructions below.
