"Mana… There is always a shortage of mana for witches. Without enough mana, witches can't advance nor use large spells that may potentially save their lives," Helia answered.
Without enough mana, witches would be forced to burn their life force, which everyone wouldn't want to do unless it was absolutely necessary.
However, Vaan shook his head.
"Mana is important, but it's not the most important to the witches in Redpine City," Vaan calmly stated.
"Most of them do not leave the city to hunt for resource in the wild, so the dangerous situations they encounter outside does not exist for them. They wouldn't need to fight for their lives in the city. If we are looking at potions that increase mana capacity or mana recovery, there would only be a portion of outgoing witches that actually need it. Mana itself isn't as important to city witches."
