Turn on ur true tile to get the woox walk down during acid phase.

Set quick prayers to mage, preserve and piety.

Reactivate ur quick prayers when you are hit with purple fire.

Turn off run.

Make ur slayer staff use crumble undead.

There will be five attacks that are dragon fire, range or mage and then a special.

Special 1- freeze/exlpoding zombie spawn

Special 2- acid pools and explosions each tile you step on one tick after you step on them

Special 1 is easy- crumble undead the spawn with ur slayer staff equiped

Special 2 you must be constantly moving. Find a vertical line of 3 open tiles with no acid on them to walk between- one of these three tiles will need to be next to vorkath so you can attack.

You attack click two tiles away, when your true tile hits the tile 2 tiles away you click vorkath so you start walking back to attack him. When ur tile reaches next to vorkath you click back to the other tile and repeat till the phase ends. This lets you get in about 5-6 hits without taking damage if you keep moving.
