As of The Elder Scrolls Online: Tamriel Unlimited v1.3.0.0 update, we have been graced with the feature of scrolling combat text (finally)! However, there isn't any information in-game or in the patch notes about the mechanics behind it; what each color and symbol represent. I contacted ZoS and got the
inside scoop.
Enjoy!
