Vengeance Helper

With the Thrall helper idea I ended up developing one for vengeance of lunar magic.

First you will install using the runelite plugin-hub.
After installing you will configure your vengeance helper, you should be on this screen

Config Settings

The first box works as an alert flasher, so you will see a box in the game that will flash red (if you have Photosensitive epilepsy, don't use this option).
Notify when vengeance expires
The second box will send a Runelite notification, if you don't want to just turn it off.
Only on Lunar Spellbook
The third box will hide the overlay when the current Spellbook is NOT Lunar.
Timeout Vengeance Option
The time (in seconds) after which the overlay will hide, after the Vengeance spell is cast.
