Runes were a mysterious object which had the power to materialize anything on earth.
For example, if one placed Ice Runes in an unmanned corner, it would turn into an iceberg after decades!
Such was the power of this mysterious magical item!
[Edgar's Life Runes]: This is special equipment. You can store 30% of your health bar in the Life Runes. When you are in critical danger, the Life Runes will recover your health points. Cooling time is one hour. (Note: When you achieve Advanced Enchantment, you are allowed to make up the Life Runes enchantment by yourself, increasing your maximum health bar cap up to 4%.)
Like the Rebirth Talisman, Life Runes was a life-saving artifact! The difference was that the talisman was just a one-time item, but the Runes could be used indefinitely!
