General Information

Alchemical Hydra is a lvl 426 boss located in Mount Karuulm. Hydra uses two primary attack styles, magic and range. Both styles can hit twice and do massive damage if not prayed against. He fights in 4 different phases, each signified by a different color.

Hydra is a good boss to kill if you are wanting to farm items to sell to the "OSRS Shop" for raw money instead of selling to players and is the main drop source of the Scythe of Vitur (uncharged).

Location

After your teleport you have to walk to the north, thereafter the east and finally to the north. There you can enter the door to kill Hydra.

Mechanics

Main Attacks

• Phase 1: Range, Mage, Poison
• Phase 2: Range, Mage, Lightning (stuns you in place)
• Phase 3: Range, Mage, Fire. 2 walls put up and fire that chases you around requiring you to walk.
• Phase 4: Range, Mage, Poison

What To Do

Phase 1:

When you first enter the instance, you're going to want to run to the east wall next to the big liquid container while praying range. This will position Hydra on the red pool that will disable his defences. Once you've gotten there, you'll run north and stop 2 tiles away from the wall (spot 2 in the image below). You'll stand here until he phases.

Phase 2:

Once you've gotten Hydra to around 800HP, you'll want to move to the north wall (spot 3 in the image below) to pull Hydra over the green pool to remove his defences. In this phase, he will summon lightning. Once he does, you'll run west along the wall to the final liquid container (spot 4). Doing this, you'll dodge the lightning. You'll stand here until he phases.

Phase 3:

Once you've gotten Hydra to 550HP, he'll phase to red. Once he phases, you'll move Hydra over the blue pool to remove his defences. In this phase, he will shoot 2 fire walls based on where you're standing. Once he's finished with that, he will put fire on you that requires you to move around. You will want to turn run off and walk until that disappears.

Phase 4:

At his last 25% of HP, he will go to his "Jad Phase". In this phase, he will switch the attack type he does from range to mage and back. You'll need to prayer swap to deflect the damage. After his fourth attack, he'll do a poison attack similar to phase 1.
