Dark Blue had gained two new abilities: Water Vein Block and Faith Shackle.
Water Vein Block activated Dark Blue's bloodline energy. The stronger Dark Blue's bloodline was, the more potent this ability's effects would be.
Dark Blue used its bloodline power to trigger water-elemental energy and combined it with the water attributes under its control.
The block around Sky Sea not only provided Sky Sea with mobility through the water attributes, but it could also defend Sky Sea.
Dark Blue, Sky Sea, and Gray protected the main institute of Sky City together. Sky Sea was the vessel, Gray provided concealment, and Dark Blue covered defense.
Water Vein Block improved Dark Blue's ability to carry out its defense duty.
As for Faith Shackle, Faith Application, and Faith Gift or Robbery, they were all the same type of abilities.
