The Iron Crown of Havlor is an artifact in ADOM. In ADOM v 1.1.1 and some earlier versions, the artifact can only be generated by crowning. When worn, the Iron Crown of Havlor grants a boost of +4 to Learning. In its unidentified form, it is indistinguishable from regular iron crowns. Besides wearing it, the only ways of identifying it from regular iron crowns are by magical identification means, appraising, or attempting to sell it (artifacts often have unusually high selling prices).
