One of the questions I get asked on a regular basis is how I get a separate window to track combat statistics in City of Heroes, as shown with my ice tank here:
To get this pop-up, simply open up Combat Attributes from the Power Tray
Here we have our list of the avatar's vital stats.
As can be seen, I typically monitor my Ice Tank's Smashing / Lethal Defense, Recovery Rate, and Endurance consumption.
If you Right Click on a combat stat in the main power window, there's a pop-up with an option to Monitor Attribute.
So, if I Right Click on Energy Defense and Left Click on Monitor Energy Defense..
Energy Defense is added to the combat tracking window.
Basically, you can monitor all of the vital stats of an avatar.
Have fun keeping track of your character.
