Hello, bluelitezero here.
This is a zulrah helper I made for myself to get elite void. It turned out pretty good so I thought I might share it with everyone.
Before starting, you should travel to zulrah's shrine and label all the positions using runelite's Ground Markers plugin.
Using shift, you can right click to mark and right click to label marked tiles. Mark and label the positions shown on the map 1-7.
When you enter zulrah's shrine, the chatbox message will stall zulrah until you move.
As soon as the countdown says go, you should click to run to position 1. If you time it wrong, then the helper will become out of sync. This may not be too much of problem if you start too late, but too early and you may miss important callouts. I recommend just teleporting out if you mess up.
If the server lags (When everything seems to pause for a few seconds) then the helper will become desynced. If this happens then callouts will be given too soon (Which could be a problem on the Jad Phase) If you are not confident you can do it without the helper, I recommend you teleport out at this point.
There are runelite plugins that can help let you know when you are lagging. The first is called "Metronome". It will not tick if the server lags.
Alternativly, if you prefer a silent option. You can install my Unresponsive Cursor plugin from the plugin hub. During lag, your cursor will change.
