Zulrah is a level 725 solo-only snake boss found at a shrine east of Zul-Andra. It can be accessed through Arigon's Teleportation Menu, where the boss is listed as the second option on the Boss Teleportation page.
Forms
Throughout the fight, Zulrah will continually dive into the swamp, sending out a plethora of attacks before doing so. It will then re-emerge in its next phase and continue its attacks, usually as a different form.

Special Abilities
During the fight Zulrah can summon snakelings and/or venom clouds in any form, however the phase at which it does so, as well as when during the phase, is predetermined by the rotation (see below).
Snakelings
Snakelings are monsters that Zulrah will summon during the fight via shooting white orbs. Each snakeling attacks with either magic or melee, but never both. Despite their moderately high combat level of 90, they have extremely low defence and only 1 Hitpoint. The snakeling's low survivability is made up for by their incredibly accurate attacks, which can quickly add up damage during the fight.
Protection prayers block their attacks; however, it is better to tank the snakelings' attacks if Zulrah is also attacking. It is highly recommended to bring a ring of recoil to kill the snakelings. Rings of recoil can be purchased from "Pure" tab in the General Store, located at Home (::shops).
If you are hiding from Zulrah, it is best to use this time to kill the snakelings as to lessen the need to eat and/or use recoil charges during the fight.
Venom clouds
Zulrah will spawn venomous clouds during the fight via a barrage of dark-green orbs. If a player stands within a cloud's 3x3 area, they will be dealt varying damage per tick which can add up quickly. Players will want to position themselves accordingly for each phase as to minimise the potential damage from these clouds.
While these clouds inflict venom damage, they do not envenom the player.
It is highly recommended to bring super antipoison potions to protect yourself from the venom effect. Super antipoison potions can be purchased from "Consumables" tab in the General Store, located at Home (::shops).
Rotations
At the start of the fight, Zulrah will be in one of four possible rotations, with each rotation consisting of predefined phases. It takes Zulrah about three minutes to complete each rotation. After it finishes a rotation, Zulrah will then begin a new one; it is possible to be the same rotation as the previous one. During the new rotation(s), there is a chance for Zulrah to randomly be in a phase different from the expected phase. There is also a chance for Zulrah to enter a form where Zulrah will randomly switch between mage and ranged attacks in a way that cannot be predicted and prayed against(unlike Jad form, which alternates between mage and range each attack). Because of this, it is best to try to kill Zulrah within the first rotation.
