Norsca has a very aggressively orientated roster centered around two concepts: mobile light armoured infantry and monsters. Their high tier melee infantry is able to hold its own against enemy infantry, as can their chariots, but the real strength of Norsca lies in their powerful monstrous infantry and single entity monsters, which have huge health, attack and defense stats and are especially good against other monsters.
That being said, being fairly slow and lacking almost any ranged units of their own means Norsca is extremely vulnerable to armies packing powerful missile or artillery units. They are relying on smart use of terrain and their skirmish units to allow them to close the distance.
