set_type("body");
There are different types of armour. This doesn't imply anything about the material the armour is made of... it refers to whether this item is a suit of armour, a shield, a helmet, or so on. The allowed types are:

• body
• shield
• ring - This means a ring on your finger, NOT ring armour
• helmet - This means anything you wear on your head, like a hat
• boots - This means a pair of boots.
• gloves - This means a pair of gloves or gauntlets
• amulet - This means something worn about the neck (collar, necklace, amulet, and so on)
• bracers - This means a pair of bracers (usually magical armour worn about the forearms)
• belt - This is usually a magical armour worn about the waist

set_ac(2);
This sets the Armour Class, the effectiveness rating for this piece of armour. The higher the number, the better the protection. The sample armour table in the Player's Handbook should be used as a guide in choosing this setting.

set_value, set_weight, set_short, set_long, and set_id
These work exactly like when making weapons.

set_size("light");
This indicates the proficiency Feat the MUD should check for. One of the following should be used:

• light
• medium
• heavy
