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.

Corrosive Touch

Clan Passive: Bodies will dissolve away after being fed on.

Torture your victim by boiling their blood slowly from the inside, making them drop to their knees screaming. Nearby enemies/civilians are drawn to their screams.

Recall

First Use: Mark your current location with a ward.

Second Use: Deconstruct yourself, and explosively reconstruct yourself at the marked location obliterating any enemies standing in that spot.

Blood Curse

Curse a victim. The next time they take damage, their body swells horrifically, and they explode, doing damage to all around them.

Blood Salvo

Blood of Potency

Clan Perk: A chance when feeding that the last used ability receives twice as much blood, increasing the rate at which you can perform abilities.
