It doesn\'t really do anything other than what you see come up in your system chat; that is, give the resulting number.
People use it to roleplay battles, or have \"who can get nearest this number\" competitions, usually.
To roll a dice, the command is as follows:
/roll xdx
...where each \'x\' represents a number.
For example, 2d4 means you are rolling two dice four times each. The result will be the sum of these values.
You can also roll using minus numbers, and some people know a trick using minus numbers to make the result exactly what they want.
