Patron Power Pools
Overview
Patron Power Pools are the villain equivalent of Ancillary Power Pools, and attempt to balance the Archetypes' builds. Unlike Ancillary Powers, Patron Powers must be earned by completing a story arc that becomes available for a Villain after Level 40 (the powers themselves cannot be chosen until 41). The Villain can see Arbiter Rein, who then outlines the gravity of the situation in choosing an Arachnos Patron: Black Scorpion, Captain Mako, Ghost Widow, and Scirocco. Once selected, the story arc leads the Villain on a quest to become a true disciple of the Patron, with an Accolade rewarded at the end and the PPP being unlocked within the level selection screen.
The powersets also have the same name for each patron, regardless of Archetype. There are only four Patron Powersets to choose from with any Archetype, however the powers within them are complementary to the Villain's Archetype, similar to Ancillary Power Pools.
Be very careful when choosing a Patron Power Pool. Once selected, you cannot switch power pools, EVEN WITH A RESPEC. If attempted, the respec will only offer the single PPP group that you have chosen. Also note that it is possible to play through CoV without choosing a PPP, and the power-enabled levels (41, 45 and 49) will only present the "normal" powers as choices. However, if the PPP story arc is played through, the choices do become available, and enabled in the power selection screen from a respec.
