Block

COMMAND HELP: BLOCK

Usage: block exit

Allows you to attempt to block the exit in direction exit so that nobody can leave that way. If the exit is too large, you will not be able to block it. Use 'unblock' or 'stop blocking' to stop blocking the exit (or simply leave the room). You can allow someone in the room to go past you once with 'pass name'; any member of your party may pass without hinderance.
