There are four different hero classes that you can choose from. The four classes vary widely in their attributes and strengths. The differences between the four classes are explained in detail below. When a hero levels up, its two basic attributes automatically increase by 7.5%.

Admiral - The naval attacking class. Begins with 1,250 offence and 700 defence. Begins with level 2 Naval Excellence skill and level 1 Naval Trading skill. Bireme drachmae and lumber costs are reduced by 20% for settlements with an Admiral as their hero, settlements with Admirals as their hero receive a +5% offensive power bonus against islands if the Admiral is sent on the attack, and biremes can carry 50 troops instead of 25 if the Admiral is sent on the attack.

Priest - The main exploring and defending class. Begins with 500 offence and 1,200 defence. Begins with level 2 Learning skill and level 2 Explorer's Intuition skill. Gives -10% defensive casualties to your troops if your Priest hero is at home when your settlement is invaded. Gives -10% offensive casualties to your troops if your Priest hero is sent on the invasion.

Thief - The espionage and Thievery class. Begins with 800 offence and 800 defence. Begins with level 2 Thievery skill (is also the only hero class that can learn the Thievery skill). Can be sent on spy missions. Has access to two more spies than other hero classes. Spy training costs 1.5% of your settlement's drachmae production per hour per spy rather than 2%, and spies in training receive an extra 20% experience per hour. Spies of thief settlements steal 50% more resources on a successful spy mission than spies of other settlements.

Warrior - The main attacking class. Begins with 1,500 offence and 500 defence. Begins with level 2 Battle Acuity skill. Settlements with Warriors as their hero receive a +5% offensive power bonus against non-island kingdoms if the Warrior is sent on the attack, and Warrior heroes receive 20% more experience when attacking than other heroes do.
