This is the fanmade version of the original attribute, used by Hinako Nonomiya.
The monsters of this attribute typically have effects that activate when they link attack in a similar vein to the Adventurer attribute from Dungeon World or when you have a item equipped. The items typically have the Equipment Change keyword, allowing them to perform rather unique combos with items such as using a traditional weapon item to attack on your turn and switching to an item that helps you protect yourself on your opponent's turn. In this version you also get skills if you have a certain amount of Hero in your drop zone or if a card is placed in the drop zone during the attack phase, also enter the Keyword "Switch" that allows two monsters to change position allowing them to better use their power or defense depending on the turn.
