Waterfiend

Waterfiends are the elemental cousins of the Pyrefiend and the Icefiend, and may be assigned as a slayer task by Duradel/Lapalok and Kuradal. They are found in the Ancient Cavern which can be accessed by completing Barbarian Training to the pyre ship stage. Waterfiends are also found in the Chaos Tunnels and in the Ghorrock Fortress.

Waterfiends have a very high charm drop rate, especially for crimson charms (around 80%). At Ghorrock they drop 2 charms at a time but have a halved drop rate. For this reason, they are targeted by many players who wish to level up summoning quickly, making them more popular than other crimson charm droppers (demons, dust devils, etc.).

They are weakest against crossbow bolts, but even then their defence is good. High level crossbows such as dual Chaotic crossbows, the Royal crossbow, or the Hand cannon are advised when killing them, although a crystal bow is also effective. In addition, Polypore strike is also effective, especially when combined with Dragon's breath and Omnipower abilities. The waterfiends at Ghorrock seem to be easier to hit, but also seem to deal more damage. At Ghorrock they are found on the lower floor after completing The Temple at Senntisten and are aggressive.

Trivia

 * Waterfiends had an unannounced graphical update on 5 June 2008 - with this, some of their drops changed. Then, later that day, a system update after Smoking Kills was released to remove the drop change, only to be changed once again to fix some bugs and change some of the drops that were mentioned on the forums.
 * Waterfiends gained a massive buff with the update of 17 June 2013.
 * The combat experience gained when killed changed from 983xp to 935xp on 3 July 2013.
