Strykewyrms are a race of wyrms released on 8 February 2010. With the exception of the Lava strykewyrm and the Wildywyrm, strykewyrms may only be killed by players who have them assigned as a slayer assignment.
- Jungle strykewyrm
- Desert strykewyrm
- Ice strykewyrm
- Lava strykewyrm
- WildyWyrm (historical)
- Following the Evolution of Combat, Strykewyrms are already stunned when the player stomps on the ground, excluding lava and wildywyrms.
- Also, a red circle surrounds the Strykewyrm, allowing for ease of ability use. However, if the player leaves combat stance just as they force the Strykewyrm out, this will vanish.
- Investigating a mound when not on a slayer task creates the message "Nothing interesting happens.", and the player performs an outdated version of the Think emote.
- Prior to the patch notes update of 29 July 2016, players had to go next to a wyrm mound in order to start the fight. The same patch also increased the health of the original strykewyrms.
