Baked eyeshadows are generally much more pigmented than regular eyeshadows. You can also use them wet or dry. Using them wet means a more intense/stronger look. I have Wycon Cosmetics Baked Eyeshadow in Golden Black shade which has streaks of gold within the black. This is quite a stunning shade, best reserved for evenings.
This one has to be blended nicely otherwise it can end up looking like a smudge. Because it is multi faceted, I believe it can be used on its own without combining with other shades. After all, it’s like getting tow shades in one eyeshadow, you already have gold and black so I don’t think there is a need for another shade.
