Sazed Kholin’s abilities come from his Feruchemy and his ability to store metals to burn when needed. He can access his metalminds (stored in rings he wears under his gear) to burn specific metals to get a leg up. He can tap into his pewter to bulk up and gain strength, he can tap into his tin in order to enhance his senses, etc. This all can be taxing on Sazed, but he recharges his energy between games in order to be ready to go come game time!
