Vincent had previously thought that they were already quite strong. He had saved several Legendary Magic Artifacts, Ephemeral Mana Arts, and Formation Cores, so once they encountered the Overseer, they would be able to at least trap him and take the Qheglena away from him.
That's right, this spaceship is very important for Tara and the others… As a matter of fact, the reason why Tara needed to gather some platinum coins was in preparation for this matter. Based on what Vincent understood, the Platinum Coins can actually be used to activate a few things within the spaceship that might be very helpful for them.
Well, there could be other spaceships as well but the devices in Qheglena were the ones truly important.
However, based on what happened just now, it seems that even with all his preparations, he wouldn't be able to win against the Overseer just yet.
Vincent has to think of another way to deal with this unpredictable variable.
