Hydras can be assigned as a slayer task at level 95 slayer by Konar quo Maten. There are two different types of hydras: normal hydras and the Alchemical Hydra, both of which are only found in the Karuulm Slayer Dungeon. The dungeon requires the player to wear Boots of stone, Boots of brimstone or Granite boots to protect themselves from the extreme heat of the dungeon floor, unless the player has completed the Elite Kourend & Kebos Diary. Hydras have a Superior slayer monster variant, the level 309 Colossal Hydra.

Hydras start off with a random combat style between ranged and magic 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 (or they are on their 12th attack) 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. It is recommended to start by activating the protection prayer that protects the player against the attack style they have lowest defense towards, typically magic if wearing melee armour or ranged if wearing ranged armour, then switching to the other protection prayer if the hydra starts with an attack of the other style.

The Colossal Hydra also starts off with a random attack and switches after three attacks, but its special attack happens every 15 seconds (6th attack). This attack can go through the boulder in the middle of the main area so it is recommended to run south to the rocks that you have to climb.

As normal hydras do not have a lucrative drop table, players seeking greater money and experience are better off fighting the Alchemical Hydra instead. Only kill normal hydras when not skipping the task and needing to finish it quickly.
