Cave bugs can be assigned as Slayer assignments, and require level 7 Slayer to kill. Bring food if you are below level 20, as they regenerate quickly.

Trivia[edit | edit source]

  • Although this monster appears on Free-to-play worlds in the Taverley Slayer Dungeon, it cannot be killed because it requires a Slayer level of 7, while free players can only reach level 5.
  • The large level 18 cave bugs were level 96 before the Evolution of Combat.
  • When a level 18 cave bug is killed, it appears to fall apart and explode.
  1. ^ Jagex. Mod Timbo's Twitter account. 19 January 2018. (Archived from the original on 22 January 2019.) Mod Timbo: "1/1280 if you hit the RDT, requires T4 luck to be worn in order to get a hold of it. Of course there are tons of different ways to access the RDT so it changes massively depending on what you're fighting, what you're wearing etc."
