Pyrefiend

Pyrefiends are Slayer monsters that require level 30 Slayer to kill. They are the weaker elemental cousin of the Waterfiend, but stronger than then SOME Icefiends except the ones at Ghorrock Fortress. Also, they have very similar drops to those of Lesser Demons and Harpie bug swarms. The death animation of pyrefiends was greatly sped up as of 9 November 2009.

Locations

 * Fremennik Slayer Dungeon (Fairy ring code A-J-R)
 * Smoke dungeon
 * God Wars Dungeon (level 48)
 * Soul Wars (minigame)

Strengths and weaknesses
The Pyrefiend's attack is a magic-based melee form that hits a maximum of 50 life points. This means that its accuracy is based on your magic defence, so it is highly recommended that you wear dragonhides or other Ranged armour so you take little damage from them. (Note that Protect from magic does not nullify its attack but Protect from melee does). Despite their level, they have surprisingly high accuracy, so food is recommended. It's also recommended that you either Melee or Range. The rocks on the western end of the room that used to be used for safe spots have been removed.

Like most fire-based enemies, pyrefiends are vulnerable to water-based spells. It has been confirmed that killing pyrefiends in Soul Wars does in fact count towards the slayer assignment's total kills.
