Anguish is an Ancient curse that requires 95 Prayer to activate, the highest alongside Turmoil and Torment of all prayers in the game. It can boost the user's Ranged accuracy, Ranged damage, and Defence significantly, as well as drain those of opponents, making it the strongest Ranged-boosting prayer in the game.
Anguish provides an immediate boost to the player's Ranged accuracy, Ranged damage, and Defence level. These boosts are constant and do not strengthen over time, unlike the leech curses.
Additionally, Anguish will randomly drain opponents' Ranged accuracy, Ranged damage, and Defence. These drains are not immediate but must gradually strengthen to full efficiency. They can affect multiple enemies simultaneously, provided the player is in combat with them all.
A player will gain the same Ranged and Defence increases regardless of an enemy's level or class, but Anguish cannot lower its damage or accuracy if it does not use Ranged.
Sap and leech curses cannot be used alongside Anguish.
Anguish and RigourEdit
Anguish is often compared to the prayer Rigour, which is the strongest Ranged prayer on the standard prayerbook. Rigour requires 70 Prayer, 70 Defence, and completion of the Knight Waves Training Grounds; Anguish requires 95 Prayer and the Temple at Senntisten quest.
If comparing stat increases, Anguish is not much stronger than Rigour, yet Rigour lacks the ability to drain enemy stats while Anguish can drain them strongly. Also, the healing curse Soul Split can be used on the Ancient Curses with 92 Prayer and provides another incentive to use the book.
Anguish also offers a slower prayer drain than Rigour.
