Charged Items allow the wielder to use a specific skill, regardless of Character Class, but only a limited number of times. To engage the skill granted by a Charged Item, left-click your right mouse button Skill Selection. The Charged Item skill is listed near the top of your list of available skills; left-click on its icon to select it. The skill can now be performed by right-clicking on a target. Charged Item skills have a limited number of uses, so be sure to check the item's pop-up description or the lower right-hand corner of the skill icon to see how many charges remain. If any of an item's charges are depleted, you can return to a nearby town and recharge the item by having the local Blacksmith repair it, however, recharging an item is far more expensive than a usual repair.
The Assassin is the only class to have none of her skills available as a charged skill in a suffix, meaning it cannot be found in randomized Magic or Rare items.
