Charms are accessory items found in Diablo II: Lord of Destruction. These items only need to be present in the character's inventory and identified for their magical attributes to take effect. They do not function if placed inside your character's Stash or inside a Horadric Cube (even if that Horadric Cube is located in your inventory).
Generally, smaller is actually better as far as Charms are concerned, since more can be stored in a player's inventory. However, some Magic Prefixes and Suffixes are only available on the larger Charms. There are also a few affixes that are actually more effective on Grand Charms than they are on Small Charms (+Attack Rating, for example).
When using Charms, the player may really dig themselves into a hole wherein they cannot pick up any more items. It is best to pick only the best Charms to keep and sell ones that are sub-par. Try to keep some space to pick up one or two large items. Players are welcome to completely fill their inventory with Charms, but take note that other party members may pick up good equipment dropped by monsters.
A Charm's effects are varied, some ranging from increasing one's life to even increasing the amount of Gold enemies drop upon death. It is advisable to store Life or Resistance Charms in your Stash and equip them before facing a tough boss.
Charms come in varying sizes, each size having three types of artwork, which isn't in any way related to their stats:
- Small - One inventory space.
- Large - Two inventory spaces on top of each other like a Dagger.
- Grand - Three inventory spaces on top of each other like a Short Sword.
There are only two types of Charms: Magic and Unique. Rare, set or crafted charms have not been introduced. Magic Charms contain 2 attributes at most, which increase in quality depending on the size of the charm. All three Unique Charms are associated with Battle.net-only Quests.
Charms are a sort of collector's item in Diablo II. It brings a subtle strategy in the game by forcing item searchers to decide between increased stats versus inventory space.
