This article is about the normal Slayer monster. For the boss variant, see
Alchemical Hydra.
NPC ID: 8609Combat level: 194
Hydras 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. There are two areas within the dungeon that contain hydras, one being exclusive to players on a hydra Slayer assignment. As both of these are located within the Karuulm Slayer Dungeon, players who have not completed the elite Kourend & Kebos Diary must wear boots of stone, boots of brimstone, or granite boots to protect themselves from the extreme heat of the dungeon floor, or else they will take rapid damage.
Killing a Hydra is a requirement for the elite Kourend & Kebos Diary. The Alchemical Hydra boss is task-only, but the standard Hydras found on the lower level of Mount Karuulm are not, so the achievement can be boosted using a Wild pie or other temporary skill boost.
The poison splats launched by the Hydra.
Hydras 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 dark totem pieces, 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.
