Guild Mine

“

The aetherium mine is one of the main buildings in your guild hall. The workers in your mine will automatically generate aetherium over time, which is required for most upgrades. Rekka, the mine's proprietor, offers upgrades related to the production of aetherium.

— Guild interface

The Guild Mine is run and maintained by a Mine Proprietor. It is associated with the excavation aetherium.

Acquisition

The Guild Mine will become available to build once you have completed Tavern Restoration 1. Mine Excavation 1 will setup a temporary structure in the Guild Hall while work begins on building the full Mine. Mine Excavation 2 will give you access to the full Guild Mine.

Mine rate upgrade analysis

Same level Capacity increase is required before a Rate unlock. You may or may not consider the capacity increase part of the total cost of a rate increase. "Hrs to mine requirement" is (cost / prior per min / 60 min per hr). "Extra Every" is (1 / (current per min - prior per min)) time to generate an extra aetherium. "Break even" is the time (hours = cost * extra every / 60 min per hr) to recover the cost. It is possible to dedicate most aetherium production to maximizing capacity and rate before any other upgrades, but this will take weeks. You will also need to perform some non-mine upgrades to receive the GXP required to level. Maximizing the mine rate quickly is the fastest way to build all remaining upgrades, most of which require aetherium.
