Theoretical question: If a group wanted to have their covenant aura let barren/infertile people (including Magi using longevity potions) have children, ala Immunity in the Covenants book pgs 7 or 8, would the major or minor boon be appropriate?
Within the covenant’s aura, all people and objects are immune to a form of damage, influence, or Flaw. If players designing characters pair their Flaws to this immunity, it becomes a Major Hook. Their Flaw helps define the covenant’s culture.
Within the covenant’s aura, all people and objects are immune to a specified form of damage or influence, as per the Virtue.
Since Infertility is not a Flaw, I lean towards a Minor Boon.
