Charge

Charges restrict the use of specified cast spell properties on an item. Any cast spell property can be assigned to consume a certain number of charges. When there are not enough charges left, the related spell cannot be cast from that item. An item can only have one pool of charges, but can have multiple cast spell properties that consume these charges. Once a charge is used, it can only be replenished by scripting.

Item destruction
Items that are not flagged plot are susceptible to being destroyed when a charge consuming cast spell ability causes the item to not have any more uses of cast spell abilities excluding those marked as single use only. For example, if an item had 6 charges and could cast bless for 5 charges per use and aid once per day, then using bless before aid would not destroy the item, but using aid before bless would cause the item to be destroyed. Cast spell properties that have 0 charges per use or are usable infinite times per day prevent an item from being destroyed when other cast spell properties deplete the charges, as there will always be a cast spell ability ready to be used.

Using additional charges
When charges are increased by script, a player may need to rest to take advantage of the addition, as the item will need to recalculate its remaining uses.

Scripting Notes
The number of charges on an item is returned by GetItemCharges. The number of charges on an item can be changed/set using SetItemCharges.
