When you choose your clan, you will start with a passive ability unique to each clan. You can then unlock abilities from the Ability Tree, starting with your chosen clan. Each ability requires spending Ability Points to unlock, which are earned from completing missions, combat, and exploration.
At the peak of the Ability Tree, you can unlock the clan Perk, a reward to those dedicated enough to unlock all of the abilities for a clan, giving a permanent passive upgrade.
