Grand Force

The Grand Force is a special equippable accessory item that is obtained from Stardeer Coffee in Wendy Wu: Homecoming Warrior Kick-in Challenge. It is the fourth special item the New Teenager and Wendy Wu can get if they brewed a fourth unique hot chocolate that has not been made before, after the Float Cuff. As with all Special Items, when the drink is made, Nina Wu comes into the café to take a drink and leaves behind the item as a thanks. When a Yin Warrior has the Grand Force equipped, the damage he or she deals to enemies and receives from enemies is doubled.

In-game description
''Double the damage you give AND take! (Damage Up)''

Trivia

 * The Grand Force is based on the Lightsaber, from Star Wars. The sound that plays when the New Teenager gets the Grand Force is the sound that plays when the Lightsaber is turned on.
