Quand un mercenaire augmente de niveau, il peut augmenter trois attributs et choisir un nouveau perk. Les perks représentent les spécialisations possibles pour un mercenaire : être un expert du bouclier, maîtriser à la perfection l'épée, entrer dans une frénésie meurtrière ou récupérer plus efficacement la fatigue accumulée, ne sont que quelques-uns des exemples possibles.

Il existe en tout 50 perks répartis en 7 tiers. Il faut posséder un perk pour débloquer les perks tier 2, deux perks pour débloquer les perks tier 3, et ainsi de suite.
