Tells you to use your healthstone if you have one during the Anub'arak encounter in phase 3 when your health is too low to survive a tick of penetrating cold. The player hp threshold is set to 4000, it can be changed in the settings if you like, but 4000 seems to be a good number.
It will also tell you when you are about to die if you are at or below 4k hp and do not have a healthstone. This was made so that you can quickly use a personal cooldown to survive it.
Plays a goat bleat when activated.
Use at your own discretion.
