Flames of Zamorak is a combat spell in the standard spellbook requiring 60 Magic and completion of The Mage Arena activity to cast. A player can cast this spell only while wielding the Zamorak staff, Staff of the dead, or Toxic staff of the dead at the cost of 2 Blood runes, 4 Fire runes, and 1 Air rune. Only the staff of the dead and its toxic counterpart can autocast this spell.
The spell also has a special effect, reducing the target's Magic level by 5%. The spell will not further decrease magic level if it has already been lowered by the spell, and will only reapply once the magic level has been fully restored. Since Magic level does affect magic defence, this does cause subsequent attacks to be more accurate; however, the spell's max hit will not be increased.
The base max hit of this spell without modifiers is 20. However, when a player casts the Charge spell and wears a Zamorak cape, the base max hit is increased to 30. Using a Staff of the dead, occult necklace, Slayer helmet (i) and tormented bracelet would raise the maximum hit to 44 if fighting a monster on task.
While a rune-providing staff cannot be used with this spell, a tome of fire will provide unlimited fire runes. However, it will not receive the 50% damage boost given by the tome, nor will charges from the tome be consumed.
