This is an idea I just had, seemed interesting

First of all, wanted to say that I really love the new mechanics on realm blessings and how stuff now work as 'coins' (the idols and menhirs) for the blessings.
But it occurred to me that some of the descriptions, especially the blessings related to nature, seem to connect more to the land and how the people from this realm relate to it rather than the work of the people itself (which are idols and menhirs...)
So I thought:
What if several new "coins" were added to the pool, providing for more varied "costs" for blessings... And what if those new "coins" were naturally occurring things/resources instead of things you can build? For example: Heartwood trees could be used to enact certain blessings but to have them available your realm has to have them inside your claim

That way, over time with more and varied blessings, the kingdom buffs would not only relate to the grinding for the buildable resources but also a reflection of the land itself, encouraging expansion, more value to resources rather than the item they give itself and interesting possibilities of human contact and conflict

Just a thought!
