Settlements

Settlements are a large aid in mining expeditions. The more settlements the player governs or joins, in addition to the more the player's alliance governs, the higher chance of finding motherlodes at volcanoes and ruins scattered around the world map.

If the player finds a settlement, the player may either: Scout, attack, or join. If the player attacks the settlement successfully, they will then govern the settlement. The defence of the settlement depends on the defence of the governer. For example, if the owner has level 5 defence, all the settlements they govern will have level 5 defence. If the owner upgrades to level 6 defence then, all the settlements they govern will then have level 6 defence.

If the player finds an unsettled settlement, they may take it over, and they will then govern that settlement until a fellow player manages to take over the settlement.

The chance to find a motherlode has a limit. And apparently, the minimum amount of settlements an alliance needs to obtain the max chance of finding motherlodes is 3750.

Assume the chance of finding motherlodes by settlements is organized in points. For every settlement you govern, one settlement is 1 point. For every settlement your alliance owns is 1/2 a point. For every settlement you join is 1/25 a point. It is unknown if this is true, though.
