The summoned Phantom Viper can utilize all the abilities that the paragons used. Salvos's divine ability didn't work on the defense paragon so it won't work on this phantom. That doesn't mean that Salvos is weak. He would have been able to fight the other paragons and kill them, especially the speedsters and the spell tower but the brutes and defense paragon would have shrugged off his attack.
"Is that really a good idea to leave them to attack it," Salvos asked. "It seems very dangerous."
Soverick shrugged. "We can afford to play around a little. The child of the plane has not changed anything. We are still killing the Vipers. They have only gotten a fighting chance. We will still win when it has been weakened enough. So let them play."
