I wane and wax, but never diminish. I have craters, but feel no pain. I influence tides, but have no water of my own. I reflect light, but have no fire within. What am I?

I am in three ways a shield, though only two have arms. One may be for warmth. Another for family. Lastly for a visual change.

I show you a figment of the picture's whole. I share the pigment with the purest charcoal. I'll come with you wherever you tred, but I'll never go in your stead.

All the printed symbols match The pale skin's rosy glow An overabundant wealth of cash Clean water's washing flow

One two three, you can slalom on me. Two three four, all the blood you adore. Two three, chinese philosophy. Three four, when you enter a door. Fully, I cover head, shoulder, toe knee, What am I, one two three four, from your crown to the floor?
