This is a basic threat display AddOn using Blizzards new built-in threat functions.

It displays a customizable amount of bars for everyone on the threat list of your current target.

Unlike Omen on the live servers, it will display the correct threat values even if you are the only one with this AddOn!

The default setting displays the scaled threat percent, wich means if you get 100% threat you will have aggro.

The anchor frame will change colors depending on your current threat state:

default = 0-99% raw threat.
yellow = 100% or more raw threat percentage. Likely to pull aggro.
orange = tanking, other has 100% or more raw threat percentage. Likely to loose aggro.
red = tanking / aggro.

Note: This is your maximum threat state on any mobs threat list. It's not limited to your target.

Use Alt+Leftclick do drag the frame.
The options can be accessed through the "/zt config" command or Alt+Rightclick on the frame.
