Absorbing Man's one weakness is to touch dirt. As dumb as that sounds, still not the easiest thing to do. Although I do remember them tricking him into touching it pretty easily in Guardians of the Galaxy. Which is where a lot of my initial understanding of the character comes from. Stone form was the one I remember I used to see the most. Even the design they chose for one of his figure variants.

Upper torso and arms were from Hyperion. Lower torso, upper legs, and feet were from Absorbing Man. Lower legs were Doc Samson, and the head was Wonder Man. Sculpted the boots and bottom of the pants. Cut all the hair off and resculpted the head. Sculpted the ball and glued some chain to it. From there, a full repaint, and all done!
