Or something more hard to obtain, but what matters is the function of it, that is substitute of food, i don't consider it hard enough to be an quest, but maybe something that requires an Gran-Master quest to do... and everybody can use it, it would be nice if this rune could be a Lucrative Item for those who have higher levels at Runecrafting.
Draco Burnzsaid: How would one obtain this "rune of life"?
Chance of obtaining them from GoP. Score of 50+, on a single altar (for Air Fire, or Nature), 40+ (for Water, or Body). or 20+ (for Mind, Earth, or Chaos), required to be eligible, with greater chances, and greater quantities of runes, the higher you go above that.
