Command: shield

Usage: shield <player>

The shield command will allow you to shield another being against
blows.  The shield is non-aggressive, which means that you will not hit
back against enemies attacking the person you are shielding.  Shield
works against Pk attempts while the 'protect' command does not.
As a shielder, you will protect against damage based on your
defense skill.
You can shield NPCs as well as players.
