Dungeon Master Guide Text[]
This armor is identical in appearance to armor of command and functions as a suit of plate mail +1. However, when worn, the armor causes the character to suffer a -3 penalty to all encounter checks. All friendly troops within 360 feet have their morale lowered by -2. The effect is not noticeable to the wearer or those affected (i.e., characters will not immediately notice that donning the armor is the cause of their problems).
