Boeotia is ready to take its seat of dominance among Hellenes.
Boeotia is wedged between Athens on one side and Phokis on the other.
Avoid war on two fronts! Boeotian forces can already use Hoplites, so use your military advantage. A fast campaign against Phokis before they get too strong could be successful if you time your actions well; it will give you the resources and capacity to take up a fight with a much stronger opponent - Athens - later.
Use the advantage of trade routes to your nearest neighbours, especially Euboea to gain resources to sustain the growing needs of your economy and armies.
