Waterfiends can be found in the Ancient Cavern underneath the Baxtorian Falls and in the Kraken Cove.

Waterfiends are moderately resistant to all forms of combat with the exception of crush attacks, which they are significantly more vulnerable against. They use a magic attack whose projectile resembles water blast, along with a magical ranged attack resembling ice arrows.

Duradel is the only Slayer master who assigns waterfiends, and they are an uncommon assignment. To unlock player must have entered Ancient cavern. [1]

Killing a waterfiend is a requirement for an elite clue scroll.


The simplest way to reach waterfiends is by accessing the Ancient Cavern, found south of the Barbarian Outpost. A games necklace allows for easy trips to the bank.

Because waterfiends use both magic and ranged, circumventing all of their damage through protection prayers is not possible. However, both of their attacks are rolled against the player's total magic resistance. Therefore, only armour to provide magic defence bonus, such as dragonhide or Karil's armour, is helpful when fighting waterfiends.

Using crush attacks is ideal for dealing damage. If a crush weapon is not available, some high level weapons, such as the Saradomin sword, possess a secondary crush attack which is sufficient given the very low crush defence bonus of waterfiends.

Alternatively, ranged is also effective as most magic-resistant armour also provides a substantial ranged attack bonus. Once waterfiends lose their aggression, they can be trapped and safespotted in some locations within the Ancient Cavern. The crystal bow, which has an extraordinarily long attack distance, can be used to safespot waterfiends over larger bodies of water.

Using Protect from Missiles is recommended for those struggling to defend against waterfiends.

Many of the waterfiends' drops are ideal for casting High Level Alchemy on.
