Armor and Armor Class

One of the key differences between Classic D&D and versions from 3rd Edition or later is the use of negative armor classes: the lower the number the better the protection. Though counter-intuitive, it is easy once you get the hang of it.

Armor comes in a variety of types and styles. The most standard types of armor are included in the table below. Each type of armor constitutes a complete set. The player can presume that his or her character, as part of the set of armor, gets the type of headgear appropriate to the armor (e.g., from a stout leather cap to a full metal helm). Given the abstract nature of D&D combat (not location specific for damage, for instance), the player may imagine other appropriate armor components as s/he chooses – gauntlets, vambrances, greaves, etc. – as these components do not affect play or armor class.
