This goal tells the bot to capture valleys for increased resource production in your cities. The bot will automatically know to capture forests for cities with a higher production of lumber, hills for cities with a higher production of iron, deserts for cities with a higher production of stone, and lakes for cities with a higher production of food. You will benefit more from valleys (more than 200k per hour production bonus) in a pure resource city of all lumber or all iron, rather than mixed fields with partial lumber and iron.

If config ValleyMin is present, the bot will use the config Valley setting as the maximum level valley to obtain. Using both goals in combination, any time a valley becomes available of a higher level (up to this maximum), the bot will drop the lowest level valley to upgrade to the higher one, until all valleys are of this level.

The bot will use any available hero for valley acquisition, unless specified otherwise in ValleyHeroes.
