Do we know what Seed of <Affinity>, Root of <Affinity> and Heart of <Affinity> from tier 3-5 tomes mean? They are neither improvements nor hero skills, icons near them are wrong for that. And what would happen if you first take tier 3 tome from not your main affinity, and only second tome from it? Like, for example, if I take Tome of Subjugation for unicorn riding Tyrant Knights before tier 3 Nature tome in otherwise Nature-oriented game, what would happen? Would I not get Seed of Nature with nature tome and be unable to progress further with Nature tome tree, or I would safely have two Seeds, of Nature and Order, whatever these Seeds mean?
