Enchantment

An enchantment is the bonus (or penalty) that some items have (a Leather armor +1, for example). A bonus (+) increases the item's power, and a penalty (-) decreases the item's power. A cursed item is more than likely going to have a penalty.

Armor
When an armor is enchanted, the enchantment is added to the armor's AC rating.

You can increase the enchantment of armor using a scroll of enchant armor.

Gloves

 * Gauntlets of power. These gauntlets increase your strength to 25 regardless of what the enchantment is.  The enchantment increases the AC the gauntlets give.
 * Gauntlets of dexterity. The enchantment on these gauntlets increase your dexterity and AC by the amount shown.

The enchantment on all other gloves acts the same way as for armor.

Weapons
When a weapon is enchanted, the enchantment is added to the weapon's to-hit bonus and the damage.

You can increase the enchantment of a weapon using a scroll of enchant weapon.

Rings
There are a few rings that can have an enchantment:


 * Ring of adornment.
 * Ring of protection.
 * Ring of gain strength.
 * Ring of gain constitution.
 * Ring of increase accuracy.
 * Ring of increase damage.

The ring adds the bonus to the magical property. For example, a ring of protection +2 will add 2 to your AC. You can increase a ring's enchantment by charging them using a scroll of charging or the Platinum Yendorian Express Card.

Losing enchantment
There are many ways an item might lose enchantment:


 * Enchanting an item too much will cause it to be destoyed. See scroll of enchant armor, scroll of enchant weapon, and charging for more information.
 * Getting hit by a disenchanter will decrease enchantment on weapons and armor.
 * Reading a cursed scroll of enchant weapon or enchant armor.
 * Reading a cursed scroll of charging and selecting a ring as the target.
 * Engraving with a weapon that is not an athame.

Erosion does not affect the enchantment on an item.
