You are immune to diseases and do not need to eat, drink, or sleep. Instead, you require a short rest to regain your energy, during which you must perform maintenance on your body. You can't be healed by conventional means, but you can be repaired with the Mending spell or through other magical means.

Your body is made of porcelain or a porcelain-like substance, making you vulnerable to shattering. When you take critical damage or fail a death saving throw, you must make a Constitution saving throw (DC 15). On a failure, you are shattered and incapacitated. You can be repaired with the Mending spell or similar magic within one hour, or you will need to undergo a lengthy and expensive process of reconstruction.
