Rock Worm is an Enemy in Demon's Souls.


Rock Worm Description

They are found exclusively in the second section of the Stonefang Mines; they generally remain hidden underground until the player approaches them or takes a nearby treasure, whereupon they will emerge and attack. Their rocky skin renders them almost immune to non-magical damage, except around the exposed flesh of their mouths, which are drastically less resistant to physical damage but still quite fire resistant. They attack either by vomiting magma on the player for substantial fire damage or spinning around rapidly to inflict physical damage and knock the player backwards. Additionally, there are three Rock Worms on the very bottom level of the mines which can spray magma all around them in a fountain-like motion; attempting to pass through the cluster of worms while they are using this attack is virtually guaranteed to kill the player unless he/she has extremely high fire defense or resistance. They drop all varieties of Greystone.


Combat Information

  • Pulls its head back and lunges its head forward, biting the player
  • Swings its body in a horizontal circle
  • Spits a pool of fiery liquid
  • Rock Worms guarding the pair of Hands of God: These only spray fiery liquid upwards, dealing fire damage in a sizeable circle around it



  • These guys lurk underground until you approach. Then they burst forth and begin to spit vile stuff on you. Semi-dangerous for melee guys, especially the larger ones that spit up a 360 degree fountain, they are pitifully easy for ranged guys. Use target lock and flick the right analog stick until you target their mouth. Fire an arrow or spell (soul light for massive damage) into their mouth directly and they should die in one hit, and give you bonus soul for a one-hit kill. A good time is when they first spit at you, since their mouth is stationary for a moment. Remember they are extremely weak to magic attacks, so even though their defense is strong, even just a few body slashes with a magic damage-dealing weapon will do them in.

  • If you happen to have a Greatsword of some kind, it's strong vertical slash throws a direct hit to their mouth!
