A day before his field training, Arthur opened the store to find multiple reviews and requests for resupply. The runic cards he placed, at an astonishingly cheap price, were all sold out.
He created two cards. The Heal Cards which were the more popular ones and the Detection Cards which were the less expensive ones.
Even though the Heal Rune wasn't that instantaneous, the fact that it doubled the natural healing of the body was indisputable. Stamina was the stat that governed regeneration and healing. Doubling that amount of healing for awakeners was something only high-tier potions could achieve.
For normal humans, this card wasn't that helpful. For awakeners, this card was crucial for survival. Arthur priced it at 10 Jerano points and they were sold out instantly.
