Pyrefiend

Pyrefiends are Slayer monsters that require level 30 Slayer to kill. They are the weaker elemental cousin of the Waterfiend, but stronger than 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) (When entering the dungeon, there is a direct shortcut to them, that requires 81 Agility to jump across a chasm.)
 * Smoke dungeon
 * God Wars Dungeon (level 48)
 * Soul Wars (activity)
 * The dungeons of Daemonheim(Floors +18)

Strengths and weaknesses
The Pyrefiend's attack is a magic-based melee attack. 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 negate its attack but Protect from melee does. The level 43 pyrefiends can hit a max of 44 life points, and the level 48s can hit a max of around 70. Despite their level, they have surprisingly high accuracy, so food is recommended. It is also recommended that you either Melee or Range them.

Like most fire-based enemies, pyrefiends are vulnerable to water-based spells. If using melee, it appears stab attacks are more effective than slash attacks (this has been confirmed). It has been confirmed that killing pyrefiends in Soul Wars does in fact count towards the slayer assignment's total kills.

Trivia

 * Sometimes while fighting a Pyrefiend, it is possible to have it in the same space you are standing.
 * Pyrefiends are also a possible monster in the Daemonheim Dungeons, at varying combat levels. These ones have an entirely different drop table including the Flameburst Defender.
 * Quite often when fighting pyrefiends they will seem as though they are attacking from a distance when really they are behind or in front of you.
