The Alchemical Hydra is a boss found in the lower level of the Karuulm Slayer Dungeon in Mount Karuulm, requiring level 95 Slayer to kill. The Alchemical Hydra was the creation of a Dragonkin named Karuulm. While Karuulm saw promise in his creation, he nevertheless saw it as a failure because he could not replicate its traits, and abandoned it along with his other creations: the Wyrms, Drakes, and Hydras.

Unlike normal hydras, the Alchemical Hydra can only be killed while on a hydra Slayer task, which are only assigned by Konar. In addition, as it is only found within the volcano, 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.

Players should be wary about running back to collect items after death, and make sure to bring protection against the hot floor. The damage from the floor will interrupt attempts to reclaim items, making it impossible to do so, and dying a second time will wipe the death storage.

Along with all the unique drops obtainable from hydras, it can also drop hydra leather, which is used on the machinery south-west of the pool in the Lithkren Vault to create ferocious gloves, as well as the hydra claw, which is combined with a Zamorakian hasta to create the dragon hunter lance.

The boss's lair[edit | edit source]

To reach the boss, players must run north past the Tasakaal, then east past the hydras. They will then reach the entrance to the lair by Orrvor quo Maten. Alternatively, players with level 88 Agility can reach it safely by using the mysterious pipe just behind Kaal-Ket-Jor, though this takes roughly the same time as reaching it by running past the hydras.

Fight overview[edit | edit source]

Alchemical Hydra has four phases throughout the fight, depending on its remaining health. It attacks with Ranged and Magic, alternating between them every three attacks for the first three phases. At the start of each phase, it has a 75% damage reduction, which can be removed if it is lured over a vent on the floor which spews chemical liquid. However, the vent must be the correct one, corresponding to the combat triangle (e.g. when it is green, red will weaken it), otherwise the Hydra's damage is increased by up to 50%.

When the Alchemical Hydra reaches 75%, 50% or 25% of its health (that is, at 825, 550, and 275 Hitpoints), it will lose one of its heads and change phase. The damage reduction is reapplied, and so it should be lured over the next vent. It also has special attacks for each phase: poison pools when green and black, electricity when blue and fire when red. These special attacks can be avoided, but they can be devastating if dealt with carelessly.

When the Hydra is killed, it will respawn in approximately 25 seconds.

Drops[edit | edit source]

In addition to the 100% drop, the player will also have two rolls on the Alchemical Hydra's drop table. The first drop has a chance to be a unique, while the second is always standard. The drop rates in the drop table below reflect the chance of getting an item for every roll on the standard loot table. For example, a listed drop rate of 2/100 indicates that you have two 2/100 chances of receiving that item.^[1]

Drops remain on the ground for 30 minutes, or until the player leaves the instanced area.

Drop rates estimated based on 292,738 kills from the Drop Rate Project, unless otherwise cited.

The average Alchemical Hydra kill while on a Konar task is worth 159,960.86.

^ Jagex. Mod Ash's Twitter account. 13 January 2019. (Archived from the original on 16 April 2019.) Mod Ash: "The first roll will go to the unique table OR to the standard table. The second roll will always go to the standard table. And you only get one pet roll in either situation."
^ Whether a unique item is dropped is determined by the game rolling each item in succession, and if it fails, the next item is rolled. If any item is successfully rolled, it will be dropped, and if no item is rolled, it is replaced by a regular drop. The order is dragon thrownaxe, dragon knife, hydra's claw, hydra tail, hydra leather and brimstone ring piece. For example, a brimstone ring piece rate follows the formula ${\frac {1}{180\div ({\frac {1999}{2000}}\times {\frac {1999}{2000}}\times {\frac {999}{1000}}\times {\frac {511}{512}}\times {\frac {511}{512}})}}={\frac {1}{181.07}}$

[1] Jagex. Mod Ash's Twitter account. 13 January 2019. (Archived from the original on 16 April 2019.) Mod Ash: "The first roll will go to the unique table OR to the standard table. The second roll will always go to the standard table. And you only get one pet roll in either situation."

[2] Whether a unique item is dropped is determined by the game rolling each item in succession, and if it fails, the next item is rolled. If any item is successfully rolled, it will be dropped, and if no item is rolled, it is replaced by a regular drop. The order is dragon thrownaxe, dragon knife, hydra's claw, hydra tail, hydra leather and brimstone ring piece. For example, a brimstone ring piece rate follows the formula ${\frac {1}{180\div ({\frac {1999}{2000}}\times {\frac {1999}{2000}}\times {\frac {999}{1000}}\times {\frac {511}{512}}\times {\frac {511}{512}})}}={\frac {1}{181.07}}$

Mod Munro: "As I mentioned on the Q & A, here are the pictures of the drop rates for various parts of Kebos. This time with the correct drop rate for the pieces of the Brimstone Ring."
