Slap Glove

The Slap Glove is a pair of gloves and a Psynergy-bestowing item introduced in Golden Sun: Dark Dawn. The Slap Glove is unique in that it is currently the only Psynergy item that falls into one of the major equipment categories.

In
The Slap Gloves grant the wearer access to the Slap Psynergy like a Utility Psynergy item. As a plot-important item, they cannot be bought or sold. The Slap Glove is given to Matthew by Ryu Kou in Kolima Junction, but only temporarily. They will be removed from the inventory shortly after the party defeats the Mountain Roc at Talon Peak. Like most Glove-class armor, the Slap Glove can be equipped by all Adepts, making it the only Psynergy item in Dark Dawn that is not limited to Adepts of a certain element.

As a Utility Psynergy item that doubles as defensive equipment, the Slap Glove will fall short compared to most handwear the party will have acquired by that point over halfway through the Morgal arc. Thus, the Slap Glove's main usage is for its ability to grant the plot-critical Slap Psynergy. Karis is a likely candidate for the Slap Glove, as Slap is a weak single-target Jupiter-aligned base damage attack that can Stun the target when used during battle. The Slap Psynergy is designed to be useful in the upcoming battle against the Mountain Roc, for its self-regenerating Stone Molt form will end early if Slap is used on it.

Since the Slap Glove will be taken from the player's possession in a cutscene that is triggered shortly after the battle, it is important to re-equip whatever handwear was on that Adept previously once the Slap Glove is gone. In any case, the Slap Glove becomes both irrelevant and missing for the rest of the game, as Sveta joins the party in Belinsk Ruins knowing Slap naturally.

Story
As stated by Tret, the Slap Glove is a treasure held by the Fang Tribe, the Beastmen royal family. It allows one who can't learn it naturally to use the Slap Psynergy, a unique ability notable for being the only means to awaken the Mountain Roc. In addition, it is stated in the game that one needn't be an adept to use the gloves, as demonstrated by Ryu Kou using them to get through Belinsk Ruins.

The glove appears to have been in Sveta's possession originally before being given to Ryu Kou and Hou Zan, possibly having been tucked inside Hou Ju's bag. The two Sanans proceeded to use the glove to navigate the Teppe Ruins and reach Morgal. Upon joining up with Matthew, they gave him the Slap Glove to help with the Mountain Roc in exchange for assistance in rescuing Ryu Kou's sister, Hou Ju from Belinsk. Ryu Kou, however, sensing hesitation in Matthew's party, took back the Slap Glove as well as taking the Magma Orb and a single Magma Shard in order to enter Belinsk Ruins and rescue his sister alone. It is unknown if he ever returned the glove or if he still has it.
