Lawrence of Rome’s Gridiron

Origins
Lawrence of Rome was one of the seven deacons of ancient Rome, serving under Pope Sixtus II, who were martyred during the persecution of Emperor Valerian. Lawrence distributed donations to the poor when one day a prefect was so angry with what Lawrence had done that he placed Lawrence on a gridiron to cook. After he had suffered the pain for a long time he supposedly said the famously cheerful remark, "I'm well done. Turn me over!"

Effects
Whoever touches it will become physically invulnerable to touching fire and other hot objects. They will not experience any physical damage, all skin and muscle will show no signs of burning. However, the user still feels the pain of being burnt. While it is helpful tending to an activated fire artifact, it is not a popular choice to use. Only those with strong bodies and also a strong will can power through the downside of the artifact. It has been noticed that when the artifact is neutralized, it releases a puff of a powdery like substance that automatically cools down everything in the vicinity and stops the burning sensation.
