Each Bloodline has it's own 5 unique skills. They are 3 passive and 2 active. To get those skills You need to upgrade Aspects.
Every Bloodline skill requires a specific amount of one of the four Affinities for it to be activated. More powerful skill = higher Affinity
If You've got enough Affinity in the Bloodline to unlock skill, You can keep upgrading Affinity to have higher level of the skill.


Those skills are the Absolute skills:

They are unlocked and upgraded as your total Affinity increases.
