Invulnerability Stone

Description

This mighty blue stone is made of the compactified essence of an astral deva. When you hold this stone and activate it by thought, you become invulnerable to all forms of harm and immune to magic. No status effect or debility of any kind can negatively affect you. This invulnerability persists for a number of rounds equal to the strength of the stone, but you are irreversibly aged 30 human years (or a number of years equivalent to 30 human years if your origin is especially long-lived). Each time you are aged by the stone beyond your lifespan, you receive fatal damage and all your attributes are reduced by 3 points. The reduction in your attribute is permanent and should not be treated as attribute damage. (You may activate the stone as a reaction.)
