[FAQ] • [doc]

Grotworms are monsters found on the middle level of the Grotworm Lair, which is located northwest within the White Knight Camp. They attack with melee when within melee range, and magic when you are standing out of melee range. They have an average attack speed but they can hit fairly accurately for their level. Grotworms are not aggressive towards players with Combat level above 67.

TriviaEdit

  • Grotworm is Dutch for Cave worm.
  • It is currently the only monster that drops both medium and hard clue scrolls.
  • Before an update, Grotworms commonly dropped rune items such as rune longswords, rune scimitars, and runite ore. But due to excessive botting Jagex removed most of these items and lowered the possibility of receiving these items as a drop.
