Donation cost at every level
Alliance tech is funded by members donating earned resources — never money — and the bonus is a pure function of the funded level. Caravans adds +2.5% to gather_yield per level, to +25% at level 10. It applies to every member of the alliance at once, which is what makes a donation to it worth more than the same resources spent at home.
