I'm starting to edit it gradually: I'll remove the point about the "Teapot" for now, let it live for a while; I definitely won't remove the part about the "Sphere," I'll remove the part about disconnections for now, and I'll add something about "Monster Week" and "Plague."
Here are my new thoughts about "Conflux":
"In Conflux, you are only allowed to upgrade one of the following levels at a time (the rest can be upgraded without restrictions): 1st, 6th, and 7th. The 1st level can be upgraded either after building the 2nd level of magic or starting from level 121. The 6th level can be upgraded starting from level 141. The 7th level can be upgraded starting from level 221." As you can see, it's much simpler than my initial version.
