This article is about the slayer monster. For the superior variant, see Malevolent Mage.
Infernal Mage icon

Infernal Mages are slayer monsters that require 45 Slayer to kill. They can be slain for their common death rune drops and their rarely dropped dark mystic boots and hat. When assigned as monsters for a slayer task, beware of their accurate magic attack.

Strengths and weaknesses

Infernal Mages use a weaker version of the spell Fire Blast to attack the player, so it is recommended to wear dragonhide or magic armour, which will reduce their chance to hit. Wearing Void Knight armour is a good option because of its high magic defence. The Protect from Magic prayer is recommended for lower levels, as these mages hit extremely often. Prayer flicking is an effective strategy to minimise their damage output. They are weak to ranged, so it is advisable to bring the best bow, knives or crossbow available.

(Be aware though that if you kill an Infernal Mage right before its spell animation has started it will still cast that spell even during its death animation)

  • Infernal Mages appear to be wielding a green version of the Slayer's staff, along with a set of green, decaying mystic robes.
  • They appear to be casting Fire Blast, however their max hit suggests they are actually casting Fire Strike.
  • Due to their high accuracy, damaging magic attacks, and lack of consistent valuable drops, players often skip Infernal Mage tasks.
