Strykewyrms are a race of wyrms released on 8 February 2010. With the exception of the WildyWyrm, strykewyrms may only be killed by players who have them assigned as a slayer task. There are four types:
- Jungle strykewyrm (requiring 73+ Slayer)
- Desert strykewyrm (requiring 77+ Slayer)
- Ice strykewyrm (requiring 93+ Slayer)
- WildyWyrm, a strykewyrm cousin released as seasonal content
Strykewyrms is possibly a portmanteau of the words strike and worm, thus forming Strykewyrms which sounds like "strike-worm". This is also proven during the beginning of One Piercing Note. A character mentions strykewyrms and as the quest is fully audio, the character pronounces it as strike-worm.
