This is a module for Deadly Boss Mods and it needs DBM installed for it to work.
Written primarily for the Unity Path raid group on Earthen Ring (EU), but I've uploaded it here so people can get updates and as others may get use out of it.
When the Lich King starts to cast defile, standard DBM places a skull on the head of the player that's targetted.
However, this mod takes an extra step and places a box on your screen, telling you to either run towards or away from the stairs, in green or red text.
This is the key thing, the colour of the text (apologies to anyone who is colour blind). It makes it much easier for people to instantly realise that THEY are the person who has the defile, or conversely that they don't.
There's also a bunch of "fail mod" style functionality in there, that can be enabled under the options for the module within DBM. As standard, it will report to your console, though you can get it to report to a custom channel, but you'll need to take a look at the code and edit the line that sets the channel name. :)
