Every time you cast Beacon of the Beyond / An'shuul the Cosmic Wanderer this will display how much damage all its hits did (its AoE included), and permanently save if it's a new high score as well as the unit it was casted on. Also allows for printing highscores to chat by typing "!beacon" into the Party, Raid or Guild chat for all players with the weakaura installed.
It can also announce Beacon damage to /say by toggling the option in Custom Options; disabled by default to prevent chat spam / screen clutter for people who don't like that sort of thing.
Features:
Show text on screen on Beacon casts with damage done and high score (Toggle)
Announce in /say Beacon damage done (Toggle)
React to !beacon in Party, Raid or Guild chat with Beacon damage high score (Toggle)
There's a 30 second spam protection between each supported channel for !beacon to avoid chat spam.
You can clear your High Score by clicking "Clear Saved Data" under Information.
Configured to only record hit for current content to prevent insanely high scores from critter hits / etc.
Thanks to Maerien-TwistingNether for helping me test it out <3
