This WeakAura detects if you ever bubble hearth, i.e. cast hearthstone with a bubble like Divine Shield active. If you have ever done this it will show an annoying message on your screen!
To reset this counter use the "Reset History?" checkbox in Custom Options, make sure to uncheck it again after reload otherwise the aura will not function persistently.

This WeakAura was made as a proof of concept for the Classic Hardcore community (classichc.net) who follow a community ruleset, Solo Self-Found and Death = Delete. In this ruleset bubble hearth is banned.
