Waterfiends are demonic creatures of water^[1] found in the Ancient Cavern underneath the Baxtorian Falls, as well as in Kraken Cove and Iorwerth Dungeon. They are moderately resistant to all forms of combat with the exception of crush and heavy ranged attacks, against which they are significantly more vulnerable. They use a magic attack whose projectile resembles Water Blast, along with a magical ranged attack resembling ice arrows.

Duradel and Konar quo Maten are the only Slayer masters who assign waterfiends, and they are a rare assignment. To unlock waterfiends as a task, players must have at least level 75 combat (unless they have requested Slayer masters ignore combat level requirements), and have progressed Barbarian training up to being prompted to access to the Ancient cavern as part of Barbarian Firemaking training.^[2]

Killing a waterfiend may be a required step for an elite clue scroll.

Drops

The following drop rates are provided by Jagex, unless otherwise specified.

Konar task	Average drop value
Konar task	GE	HA
No	4,022.55	1,882.95
Yes	4,905.59	2,148.97

For waterfiends in the Iorwerth Dungeon, the average kill is worth an additional 2,816.00 (or 3,699.00 while on a Konar task) due to the additional chance of receiving a crystal shard as a tertiary drop. This value for crystal shards assumes that they are made into divine super combat potions.
