Was telling Homon about this mod yesteday, so uploading for him to try out.. It can be downloaded here.

It's critical for warlocks in arena, but can also be handy for other people. It gives tons and tons of info for locks.. like spell resists, fear expiration, CoT expirations and so on.. It also gives status information on the other team.. like when grounding totems go up and down, spell reflect, cloak of shadows, ice blocks.. bubbles and so on.

The lua can also be modified to track other things. I've added a couple myself. If you have a little coding experience and want to dig up the proper trigger names, it's not hard to do.

There's no setup involved.. just install and go. There's also no configuring, so the sounds and text location can't be changed.. but it's generally not obtrusive. After using it for a while, I've become used to the sounds so I generally know what's going on without having to read the text.
