@JeremyECrawford Why is an Adamantine Armor a magical item while a Adamantine Weapon is just one made with a diferent material?

Adamantine is a material, with which you can make weapons, armor, frying pans, bunny sculptures, fence posts, and more. There is also a magic item called adamantine armor. The existence of that magic item doesn't erase the fact that other things can be made with adamantine. #DnD https://t.co/E38DILb4VX
