Ultimate Alchemical Hydra OSRS Boss Guide

Alchemical Hydra OSRS Guide

Setup 1
(27 kills/hr)
Standard – Fire / Nature

Advice/Info
● If you don’t have the elite tier of the Kourend & Kebos diary completed, you need some form of protective footwear. Boots of Brimstone are the best option for this.

● Cape slot: Max Cape → Ranging Cape (t) → Ava’s Assembler. With Divine Potions, you won’t lose any max hits by losing the Ava’s Assembler and thus the prayer bonus from the Max Cape/Ranging Cape outweighs the minimal accuracy increase of the Assembler.

● Since the Hydra’s defence is so low, it is generally better to optimise your prayer bonus in order to stay for longer trips rather than maximising your range bonus. This can be seen in the Max Cape/Ranging Cape (t), Devout Boots, Ring of the Gods (i) and Crystal Armour. If you don’t have any of these, simply use the next best alternative (Ring of Suffering (i), Armadyl Armour, etc.).

Mechanics
● In order to do full damage to the Hydra you will need to lure it onto the vents:
Green Hydra → Red Vent
Blue Hydra → Green Vent
Red Hydra → Blue Vent
An easy way of identifying that you have done it correctly is by looking above the Hydra’s head. He will say Roaaaaaaaaaaar! when his defences are lowered.

● The Hydra will start each kill with a random attack style and switch every 3 attacks (NOT including special attacks such as Acid, Lightning and Flame Trail).

● The final phase of Hydra (the black form) will attack you in an alternating pattern, it will start with the OPPOSITE of what the last attack it threw at you was. For example if it throws a range attack before the phase change, the first attack will be a mage attack.

Inventory
● If you are not confident with being able to do long trips, take 2 Divine Ranging Potions, 8 Super Restores, 1 Antidote++ and 12 food.

● The Crystal Dust is so you can make extra Divine potions from the potions that the boss drops.

● The Bonecrusher Necklace can be used in 2 ways. One way is to have it passively in your inventory to stop the floor from getting cluttered. This will give you the prayer experience but no prayer points in return. The second way is to either equip it just before hydra dies (if you have it activated) or to equip it before burying the hydra bones on the ground if it is de-activated.

Weapon downgrade & DHCB vs Toxic Blowpipe
● If you don’t have a Twisted Bow, then you should take both of these weapons. Use the Dragon Hunter Crossbow with Ruby Dragon Bolts (e) and a Twisted Buckler until the Hydra is at 22%, or ~240 HP then switch to your Toxic Blowpipe for the rest of the kill. 22% is the perfect value for Amethyst Darts, if you’re using Dragon Darts then switch at 38.1%(420) HP. Don’t take Diamond Dragon Bolts (e).

● If you don’t own a range strength boosting shield, bring a Book of Law instead.

● When using these weapons, you should be using the Ava’s Assembler only if you’re using dragon darts.

● You can expect around 23-25 kills/hr using the blowpipe and/or DHCB.
