Ok first off what char were you using.
If you were using any mf char then its pretty easy to work out what your wearing by looking at u, especially if your a mf sorc because they're mostly all the same.
If you were a zon wearing gaze shaft etc thats also pretty easy to work out
Its if you were lowish to mid lvl and wearing lots of random stuff then its hard to work out.
Also did he tell you what charms you were holding? if not then it was all guess work and judging
hoped that helped
