How the Chronoserpent fight works: 20 Health Bars, six Phases and Vigor

The Chronoserpent has 20 Health Bars, with a new Phase rule about every four you clear. Interrupting his attacks and punishing Specials earns Vigor stacks, and without them the fight drags on. He flips between Major Mode (+50% Combat Power Rate) and an aggressive Minor Mode with Block Penetration. In the last Phase only a Special can knock him out, and only while you hold two or more Vigors.
