It’s a pretty wide variety of values., the specific command (getvalue) to the handler ([COLOR=rgb(51,51,51)]HandleDebugGetValueCommand) and then returns the target’s value of the key you specified. Similar to .npc info, but for specific values. Though the .debug has a wider scope than .npc info.
If you google ".debug getvalue mangos" you get quite a log of hits, [good example](http://webcache.googleusercontent.com/search?q=cache:00wthBmQWX4J:www.ownedcore.com/forums/world-of-warcraft/world-of-warcraft-emulator-servers/wow-emu-guides-tutorials/283544-macros-mangos-using-debug-modifying-your-character.html+&cd=2&hl=en&ct=clnk&gl=us).
Thanks for the answer, it’ll help me to find out more. Nonetheless I wonder if there shouldn’t be a thorough documentation for this (and other stuff). There you have powerful tools for development and testing, but you can’t use them properly because you don’t know what they are for and how to operate them. Seems a bit nuts.
