Just a quick thrown together basic guide for those interested in killing the Alchemical Hydra
The setup im using works for me you may wish to swap things around until you find the combo you like best
Bracelet of slaughter is recommended to swap to for the final kill to lengthen your task at hydra, Dramen staff not needed if elite diary is done and you can tele without it, can swap out sharks and pots ( Range, Antivenom+ & Stamina ) for brews and sanfew serums for prolonged trips at a higher cost.
YOU WILL ALWAYS NEED BOOTS OF STONE OR GRANITE BOOTS TO AVOID TAKING DAMAGE JUST BEING IN THE CAVE FROM THE HOT FLOOR
Easiest way to reach Mount Karuum is via fairy ring CIR, Skills necklace or Farming guild teleport with 99 farming
To Reach the hydra lair go down the elevator in the middle of the mountain, once inside the layout is like this
The hydra has 5 forms all up in the first form it is Grey, Second form is Blue, Third form is red, Fourth form is also red and the 5th form it will turn black.
In order to attack the Hydra you must lure each form over its respective grate first so the chemicals spraying up will 'deactivate' the hydras protection, the grey first form must be lured over the red grate
The second blue form over the green grate
And the third form over the blue grate
After the third form you no longer have to lure it over the grates
In the first 3 forms it has both a range and mage attack aswell as a spitting poison across multiple squares randomly, in the first 4 forms the hydra will attack with 3 of the same attack style in a row before switching to the other, The magic attack send out 3 thin projectiles and the range 1 single larger projectile. ( The poison attack doesnt count towards the attack switching mechanics so if your on two range attacks then the poison the next hit will be the third range attack )
The second form ( Blue ) also has an electric attack that spawns in multiple locations and chases you around you must outrun these or you will be unable to move for a small period and take damage of up to 20hp
In the fourth form ( Red ) the hydra will walk to the middle of the room and shoot out 2 walls of fire essentially blocking you into a small section of the lair and then shoot out a single flame that will follow you around as you run damaging you with every hit until it runs out.
Once you reach the fifth form the hydra turns black and will alternate every attack between mage and range similar to the jad phase but is guaranteed to swap
Without the correct pray you can be hit for upto 40+ so try to concentrate your switching after every kill
If you do die here you can collect your items for a 100k fee from just outside the Alchemical Hydra room, remember to grab another pair of stone boots before you go to collect your stuff otherwise you run the risk of dying and losing your stored items!
Happy hunting and goodluck! Has been many years since ive written a runescape guide if you have any suggestions let me know
