Brynner, in a Item, there is three sets of restrictions.
Red: Means which Classes can use it, the value is in Hexadecimal, for your needs, don't touch it.
Blue: Means wich Types of Classes can use it.
Plus the values you want to make it work. For what you asked, the value must be changed to 3 (1 + 2 = Normal and Reborn Classes) or 7 (1 + 2 + 4 = Normal, Baby and Reborn Classes).
Green: Sets wich gender can use the item, 0 for male, 1 for female and 2 for both.
Good luck.
