Relics are often defined separately with their own item IDs, but not always. Items have minimum (base) stats defined, but their quality can add some random bonus effects, or bump up the existing base effects, again by a random amount. I think (further research pending) that doesn't affect base stats,  provides a small bonus,  provides a greater bonus than. The list of bonuses can confer is separately defined with specific values.
