Templar concept art.
Kormac is a melee fighter, able to absorb a large amount of damage thanks to his heavy armour whilst at the same time supporting the player with his skills, and is in many ways similar to the Paladin class of Diablo II. Throughout the game Kormac collects Templar relics and uses them to acquire greater purpose and power.
He is able to equip shields, one-handed axes, daggers, one-handed maces, one-handed spears, one-handed swords, two rings, one amulet, and Templar-specific items, called relics.
"The templar are holy warriors, fighting for justice and eschewing the dangers that lead to cultism and demonic possession by espousing self-denial. They do not merely pay lip service to protecting the realm - they are battle-trained and experienced to a man, and the brooding, dedicated Kormac is a paragon among them.
Kormac came to the order as a young man, and was quickly molded into the ideal templar, adapting naturally to an ascetic way of life. His devotion is particularly unshakable, even for one of his order, and, despite his respect for battle prowess, his disdain for those who don't share his high moral standards is readily apparent.
Though Kormac's ways will not always be your own, your aims and goals align, and so he will fight alongside you to purge the world of the insidious darkness that would hide from the light of Heaven"
