Constantine the Great, also known as Constantine I or Saint Constantine, was a Roman Emperor of Illyrian and Greek origin. As emperor, Constantine enacted administrative, financial, social and military reforms to strengthen the empire. He restructured the government, separating civil and military authorities. To combat inflation he introduced the solidus, a new gold coin that became the standard for Byzantine and European currencies for more than a thousand years. The Roman army was reorganized to consist of mobile field units and garrison soldiers capable of countering internal threats and barbarian invasions.
Constantine is a great legendary infantry commander in Rise Of kingdoms. If you can then get him especially if you are defending structures in KVK and AOO. He is insane for defending.
Problem with Constantine is that he lacks rallying skills but that is why he is great for defending. He is also a great commander to have for field battels.
His skills will transform your infantry units to unkillable troops. A 40% increase in health is insane especially for defending.
His fourth skill is great for the Ark Of Osiris. The problem with this skill is that can be triggered only once an hour while your troops are out of the city. That is why when your skill is activated you must go back to city. When you leave your city your Constantine will be able to use this skill again.
Overall Constantine is a great commander to have especially if you are defending buildings a lot and if you are an infantry player.
You can test other commander but the best commander for Constantine is Richard.
You can use it if you are getting swarmed by a lot of troops by still I would use Richard.
Martel is great with Constantine for field battels if you do not have Richard max.
