A Castle wars brace is a bracelet that aids the player in Castle Wars. When players wield this item at the moment they enter the game, they do an extra 20% damage against a bearer of a flag, and bandages heal 50% more. Players only need to be wearing it up until the time the game starts. After that, the charge is already given, and the player can switch to any item to be worn in the Hand Slot.
The brace can have a maximum of 3 charges. Each game will use up one charge, and after all charges are gone it will be destroyed. The number of charges remaining is displayed in brackets in the item name.
It currently costs about 509 coins for each use of a castle wars brace. If the player sells the bracelet with one charge on the Grand Exchange, 3305 coins could, in theory, be gained.
