Hydra are draconic creatures found in the lower level of the Karuulm Slayer Dungeon in Mount Karuulm, requiring level 95 Slayer to kill. They were created by an unnamed dragonkin as a project which is not based on any prior work done by his fellow kin.

Hydras are only assigned as a slayer task by Konar. As they are only found within the volcano, players must wear the boots of stone, boots of brimstone or granite boots to protect themselves from the extreme heat of the dungeon floor. However, players who have completed the elite Kourend & Kebos Diary can wear any type of footwear without being rapidly burned. There are two areas within the dungeon where players with and without a hydra slayer task can kill them.

The poison splats launched by the Hydra.

They start off with a random combat style at the start of the battle, switching after three attacks, regardless if they hit or not. If the hydra still persists after roughly 30 seconds into a fight, it will spit poison at three random tiles (one at the player's location, two elsewhere), dealing 4 poison damage every two ticks (or 1 to 2 damage if the player has poison immunity) when the player is standing on one. The initial splat has a 3x3 AoE.

Hydras can drop their eyes, fangs and hearts, which are used to create the brimstone ring. Much like abyssal bludgeons, the body parts are dropped in order and additional body parts can be obtained once players have one of each part.

In addition, they can also drop their tail, which is combined with a dragonbone necklace and a bonecrusher to create the bonecrusher necklace.
