The Rhodian menace grows.
Epirus moves to attack the Roman fleet, they were caught offguard and their fleet too was utterly crushed. Yet while Epirus pooled their resources to attacking Rome's fleet, Rome managed to take the Epirote capital.
Also, I had not clarified in the rules, but the bonuses instead go towards attacking and defending when you use a fleet, so the defender doesn't have an advantage with two rolls.
