Waterfiends can be assigned as a slayer task at 75 combat level by two Slayer masters, Konar quo Maten and Duradel. Waterfiends can only be assigned as a slayer task after being granted access to the Ancient Cavern. They are found in the Ancient Cavern, Kraken Cove, and Iorwerth Dungeon. Iorwerth Dungeon is only accessible after completing Song of the Elves.

Waterfiends attack with Magic and magical Ranged so protection Prayers cannot be used to negate all of their damage. However, both types of attacks roll against the player's Magic Defence, so armour with Magic Defence bonuses, such as fortified Masori armour, Eclipse moon armour, or Dragonhide armour is most helpful when fighting them. A saturated or imbued heart can also help slightly increase magic defence. Protect from Missiles will be the most helpful if they are dealing too much damage.

Waterfiends have low crush Defence, so crush weapons are recommended, such as an Soulreaper axe (on crush), inquisitor's mace, or abyssal bludgeon. Ranged can also be used in the case of Ranged armour being used to defend against their attacks.

Waterfiends do have a 100% elemental weakness to earth spells, which makes maging them generally faster than meleeing them, but at a greater cost. Using non-earth magic is only recommended if player has either Eye of ayak or Tumaken's shadow.

Bringing runes for High Level Alchemy is recommended due to their somewhat common armour and staves drops.

Because waterfiends have moderately high stats and are fairly accurate, it is advisable to skip their tasks. They do not provide as many valuable drops as other preferable Slayer monsters, aside from the Mist battlestaff for Ironmen. It is not advised to block waterfiends, as they have an incredibly low weight value of 2, thus making them very unlikely to be assigned.

1. ^ ^{1.0 1.1} Only while on a Slayer task.
2. ^ On Crush
3. ^ Emberlight scales extremely well with Melee strength gear, so its effectiveness relative to other weapons can vary significantly

Using magic can be beneficial since it allows safespotting waterfiends in some locations. If using any of the one-handed weapons, it is highely recommended to primarily use Confliction gauntlets to benefit from its passive effect, and only switch to Expeditious bracelet just before a waterfiend is about to die. Bringing Saturated heart is also beneficial for both higher damage output, and for higher magic defence if not safespotting.

Use Earth surge if using Harmonised nightmare staff, and Earth Wave if using Twinflame staff.
