This is actually kind of a big deal, getting Vernos to 7* is something that takes 10x the effort of any other hero.
(maybe except for people that had thousands of SS to throw at him at the day of his release)
Iv'e just gotten mine to 7* for the sake of completion but I feel totally disappointed. Even maxed him at O+2
Because why the hell not.
If there is ANY old hero that deserves a "holy shit" type of awakening - its definitely Vernos. Hands down.
