Character progression The character progression system in Darkfall Unholy Wars is based on prowess. Prowess can be gained from any game interaction. The amount of prowess that a player gains depends on the difficulty or rarity of each achievement. It can be used as a form of currency to acquire different skills and boosters while spending prowess is the only way to improve the character's attributes, combat, and harvesting skills. Roles and skills The new roles system introduced in Darkfall Unholy Wars requires the player to pick up a role, along with 2 schools from that specific role. One of the schools is set by the player as the primary and the other as the secondary, and each school contains 4 skills/spells, and the ultimate, the most powerful in that school.The biggest difference between the primary and secondary schools is that you can only use the ultimate from your primary school. The skills/spells available in the secondary school have full potential, but require more mana and stamina, and have increased cooldowns and charging times compared to the primaries.
