Evony Age 2 Guide

The machinery technology in Evony increases the percentage of fortification units that are repaired instantly after a battle. It says in the description of the technology that every single upgrade enhance repairable rate of fortified units by 100%, it does not however say anything about what percentage of units is repaired if you don’t have this technology at all. 100% increase with machinery technology would tell you nothing if you don’t know which number to increase by 100%.

Through testing this it seems that it is about 3% of the units that are repaired with a machinery technology of level 1, and this number would increase by 100% for each extra level of machinery. It doesn’t stack, so it basically means that 3% more of killed fortifications area repaired for each level, stopping at 30% repaired for level 10 machinery. It doesn’t seem to be quite exact, but this is very close to how it works at least.
