Nightmare

Nightmares are Slayer monsters that are unlocked after completion of Children of Mah. They require 80 Slayer to be harmed. To be assigned as a task, the player must purchase the ability from a Slayer Master for 50 Slayer reward points.

Mechanics
Nightmares normally attack with melee. They can charge up a slow-moving special attack that deals over 4000 total damage in two simultaneous ranged hits. The damage from this ranged attack can be reduced to under 1000 damage with Protect from Missiles and Deflect Missiles.
