Classes in Divinity: Original Sin form the basis of the two Source Hunters Abilities, Attributes, Skills and Talents. Additionally it determines the two Hunters weapons and armor.
In total there are eleven classes, which fall into one of three groups: Warrior, Mage and Survivor. Each class will allocate a total of 5 points to each player characters' Attributes.
Warrior classes focus primarily on physical attack and defence and as such, are best suited to close quarters combat.
The fighter is a brutal warrior and expert in close combat. However, the knight is specialised in war tactics, and trained not only to fight, but to rally troops.
Mage classes abilities stem from the various magic schools, most prefer to use long range attacks or summons, with the exception of battlemages, who use a mixture of close and long range techniques.
Survivors rely in fast attacks and skills such as theft and lock picking to complete their objectives. Their primary interest is in their well-being and self preservation.
