I hope Geomancy has very little to do with upgrades and creation. I don't want to work a long time (e.g. Minecraft) to get to level 30 to get the best enchantment to end up with Bane of the Arthropods. Chance is a bitch.
However, storytelling, or quest-giving, would be cool to see through Geomancy. Just not Geomancy for things that take my money/experience/time.
