Protect (Combat command)
The protect command lets you protect a given player against attacks
by monsters but not players. If you are protecting another player, then
when you are in the same room as that player, all weapon attacks against
that player will hit you instead. Spell attacks will not be stopped.
You cannot protect a player against another player.
'Protect' is an 'active' command: if the person you are protecting
gets in combat with an NPC, you will get in combat with that NPC as well
