Strategy to safespot Wyrms — Wyrms south/south-east of marked white tile can be attacked from a white tile and dragged next to it. Once the wyrm is lured there, player should run to marked blue tile and proceed to kill the wyrm from there.

Wyrms are draconic creatures requiring level 62 Slayer to kill, found in the lower level of the Karuulm Slayer Dungeon in Mount Karuulm as well as in the Wyrmscraig Cavern after partial completion of Fallen From Grace. Players can travel to Mount Karuulm quickly by using the fairy ring CIR located south of the mountain. Players can also directly teleport to Mount Karuulm with Rada's blessing 3 or 4. Wyrms located in Wyrmscraig Cavern can be accessed easily using a Slayer ring teleport. When fighting the wyrms located in the Karuulm Slayer Dungeon players must wear the boots of stone, boots of brimstone, or granite boots to protect themselves from the extreme heat of the dungeon floor. Players who have completed the Elite Kourend & Kebos Diary do not need to wear this footwear to avoid being rapidly burned.

Wyrms do not require any form of dragonfire protection. When encountered, they will be slithering on the ground. However, once attacked, they will levitate off the ground and attack the player. They can still be hit with melee. Wyrms attack with both Melee and Magic; however, if attacked from a distance, they will only use their magic attack. This makes the Ranged attack style while using a form of magic protection, such as Protect from Magic, or armour with high magic defence bonuses like dragonhide, a viable method for killing wyrms.

Wyrms are vulnerable to the effects of dragonbane weapons, which include the dragon hunter lance, dragon hunter crossbow, and dragon hunter wand. In the Karuulm Slayer Dungeon, a dwarf multicannon cannot be set up, as the message "The electricity here is too powerful for you to set up a cannon here" will appear; however, it can be used in the Wyrmscraig Cavern. They are also immune to both venom and poison. When leaving their idle stance, they will clear any burn effects.

They are the only monsters to drop the dragon sword and dragon harpoon. Killing a wyrm is required for the Hard Kourend & Kebos Diary and is an Easy Combat Achievement.

Trivia

Wyrms, from the Old English word meaning "serpent", are legendary dragons in European mythology. Unlike the wyrm's in-game model, wyrms were described as legless in early Germanic sagas.
Being a wingless, four-legged draconic creature, the wyrm resembles depictions of the Lung or Chinese dragon
Colossal wyrms were an ancient race of dragons, said to be capable of destroying cities and armies on their own. They slowly disappeared due to their heavy involvement in the God Wars. The current wyrms in the dungeon are a new attempt at the wyrm project by a Dragonkin named Karuulm.
