This weak aura is a designated weak aura to help raiders on Anub'Arab inside Trial of the Crusader.
It is built around the strategy for dealing with Penetrating cold always going on Tank.
Current version, there is a timer, and a text announcing to go to tank.
Secondly there is a trigger to use healthstone when having debuffs + dropping below 10%. (Accompanied by an airhorn)
This will help you survive until you get underneath tank for splash healing.
