Let me begin by saying I'm not that experienced with mining and this is just my potentially very flawed understanding. With that said, I've been looking into the orb of confinement city improvement for Targossas for a long time now, and it seems like the obsidian upkeep requirement is rather high relative to the spawning of obsidian lodes. From what I understand about mining, lodes only spawn when the commodities are used. So if the majority of the obsidian is mostly sitting in people's inventories, lodes will only spawn at the rate that enchantment goes through obsidian. Even if you get a majority of the obsidian lodes, I think the obsidian upkeep is a bit too high. I love the idea of a city being restrained by what commodities they can bring in, but with the numbers I've been given, it's too close to unsustainable. Am I totally wrong about this or can the orb of confinement use some adjustment in terms of upkeep price?
