This simple addon will show you a nice big icon to let you know when the Shadowsword Berserkers on the M'uru fight gain the "Flurry" buff, increasing their attackspeed by 100%.

I found it helpful to know about this when i was assigned to heal a tank on these mobs, as i would then switch to max rank heals for the duration of the effect.

How to use:

The addon is turned on with the "/muru on" slash command. (and turned off with "/muru off"). You will see a tiny black box on the topleft of your screen with "Muru" written on it. Shift-Leftclick it and drag it where you want the warning to show.

Then target your assigned tank and rightclick into the box, it will now show that tanks name instead. This step is important because it lets the addon know which berserkers to warn you about.

You are now good to go.

Enjoy M'uru!
