Alchemical Hydra
Warning!
This page is inaccurate or incomplete
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. Unlike normal hydras, the Alchemical Hydra can only be killed while on a hydra Slayer task, which are only assigned by Konar, Duradel, and the Mysterious Adventurer. 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.
Fight overview
Template:Alchemical Hydra/Strategies 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.

KILLING ALCHEMICAL HYDRA
Firstly, get in the safe spot position in the south-east corner of the Alchemical hydra room. You can stay here the entire fight.
The Alchemic Hydra can attack with two attack styles.
- Magic = Looks like 3 lines of streaks
- Range = Green arrow
The Alchemic Hydra does 3 ranged attacks, then 3 magic attacks, the order in which it attacks is random. Sometimes it also spits out toxic waste, you don't have to worry about it when you're in the safepot. But this does not count as either a ranged or magic attack. Let me give you an example. Hydra attacks in this order: R-R-R-TW-R-M-M-M. Even though Hydra has already done 3 ranged attacks, a Toxic Waste attack will let Hydra do one more of the attacks it was previously doing. This also works the same way for magic, in this case it may do even 4 ranged or 4 magic attacks.
Hydra has 4 phases. I will explain them down below.
Phase 1: 100%-75% HP. Cycles between 3 ranged and 3 magic attacks. (It's random what attack style is first)
Phase 2: 75-50% HP. Cycles between 3 ranged and 3 magic attacks. (Starts according to where it left off)
Phase 3: 50-25% HP. Cycles between 3 ranged and 3 magic attacks. (Starts according to where it left off)
Phase 4: 25-1% HP. The Alchemic Hydra is now enraged. Cycles between 1 ranged and 1 magic attack. (Starts according to where it left off)
