Using this ability, Keagan will be able to mimic earth, dirt, sand, dust, salt and sugar. He will be able to transform his entire body into various granular states, in which he will be able to flow and reform around injuries without permanent damage. He will be able to return to normal even if some of his grains are removed or separated, but if too much is lost he will be trapped in this form, possibly permanently. If he is touching a person or object at the time, he will also be able to transform that person or object.
