Muspah are unlocked after completing Fate of the Gods. They are found in Freneskae in the Cradle where they were originally encountered during the quest. The fastest means of reaching the world gate to enter Freneskae is by teleporting with a Sixth-Age circuit after having this teleport added by the Guthixian High Druid. It should be noted that Muspah have 100% accuracy, and do not seem to be affected by protection prayers.
