Core:Aging

While adventurers tend to stay fit well into their later years, everyone eventually does grow old. When a creature nears the end of the normal lifespan for their species they will have a harder time dealing with the rigors of a life spent traveling and fighting.

Once a creature has reached 80% of their species' lifespan, age starts to factor their health and revival chances. They gain a Thin Soul. At 90% of their lifespan, they gain a Frail Soul. Once they reach their maximum lifespan, they automatically PD the next time they die. Additionally, they die the next time that fall asleep or unconscious.

Some creatures, such as elves and undead, have an Infinite Lifespan. However, they can still suffer the consequences of old age if they are sufficiently withered.
