Lola's Plan
"It's not like that… In fact, I want you to get stronger… These three potions are quite special and have very strong effects. If the information you've given me before is correct, consuming three of these every two days for two years, or even less than that will probably be enough to reach your peak strength again."
Vincent explained. At his current level, considering all his usual activities, he can only make six or seven +10 potions in a single day and he needs to push the limit of his Pseudo-Celestial Energy to a critical level to do that.
Of course, he can't do it every day since he also has other things he needed to enhance. He also has to ensure that he always has energy reserves in case of an emergency. With that in mind, Vincent decided to just supply Rem with +8 potions or an occasional +9 potion and give the best ones to Tara.
