This command can allow you to increase the rate at which you recuperate your strength. In doing so you can do nothing else though. Type rest and wait. This of course could mean you time out so you can reconfirm the fact you are resting by entering '!' at regular intervals. If you type in anything else apart from a ! after the initial rest then the rest is over automatically. This is important as the longer you rest for, the better your recuperation becomes. Even typing rest again means you stop resting, get comfortable and start all over again. While resting, if you are looked at then other players can see you are resting. A common question will be how much extra do I recuperate? Well you will recover hp and mp back at different rates depending on your class. A barbarian only recuperates additional hp as he has no mp. A mage is at the other extreme only recuperating mp. Other classes recover some of each.

Examples :

:rest
You lean back to take some rest.
:!
You continue to rest and recuperate.
