How do you add the result of a dice roll to initiative?

To begin with, if you are using a system created specifically for the game you are playing, look through the character sheet to see if there is a Initiative button. Very often, the creator of the system has provided it.

If not, you can roll any dice and add the result to the initiative by tagging the roll with [initiative]. For example:

/r (3d6 + 5)[initiative]

If you are logged in as a player, this formula will automatically add the result of the roll to the turn order with your character.

If you are logged in as a GM, an empty entry will be added with the result of the roll to the turn order.

Restrictions

A technical limitation is that the GM must be connected to the table for the initiative to work. An initiative rolled by a player at the table while the GM is not logged in will not be added to the turn order.
