Alchemical Hydra

The Alchemical Hydra is a five headed hydra with a combat level of 426. The boss has four different phases and will have different type of special attacks in each phase. Level 95 slayer is required to enter and attack the Alchemical Hydra.

The Alchemical Hydra uses both ranged and magic to attack players. It changes its attack style every three attacks, whether if they hit or not. Both these attacks can be fully negated by using Deflect Missiles and Deflect Magic prayers. After every three normal attacks, the Alchemical Hydra will perform a special attack.

The Alchemical Hydra has a heavy damage reduction in the first three phases. The damage reduction can be removed by having chemical sprayed on the boss - which happens when the boss stands on top of the pools. Read below for more information.
