If we're talking about a spellcasters' club:
Club of Enchantments
Requirements: magical abilities
Effects:
— Mandatory spending of Action Points once a month on (automatic?) learning a new spell/creating one's own spell or magical technique/creating a magical item.
— To learn a spell, you need a book, scroll, or a character who can already cast it. In the latter case, the character gains experience.
— As an alternative to the first point, creating an item or spell/technique requires investing a certain amount of resources and can only be done once. Or once a quarter/half-year/year. As an option, instead of finances, it requires an additional investment of Action Points.
— Learning magic does not require Action Points or -10% to the cost of learning spells, if this bonus already exists.
For now, something like this comes to mind, although it's far from ideal. Let Fragment describe the techies' club.
