Syntax:
sneak [direction]
This command is used to attempt to leave or enter a location without being seen. When done properly, it can be used to get past people without their knowledge. Factors affecting sneak are current light, character size, number of characters in a room, and other similar factors.
Syntax:
sneak approach [direction]
This command is similar to the approach command, except that your character will approach the direction stealthily and stop before leaving the area.
Note: sneak can also be used to sneak to a person, NPC, or object in the room. It is not limited to simply sneaking between rooms. For example, sneak bear will allow you to stealthily approach something named 'bear'.
