Big Spoiler?: When to use High Class Scrolls

He is one of the new story characters introduced at JP ver. 2.2.10. He is quite different from other characters in a sense that he can reincarnate when he grows at Lv. 60 or higher and his Light point will be increased by 1 every time he reincarnates at Lv. 80.*

As I mentioned elsewhere, there is a sort of Another Dungeons where Light/Shadow requirements per reward slot are inflated to the maximum of 360. Under the situation, he can be a "Light Saver" to boost the total Light points of a party.

The number of High Class Scrolls is 38 when you raise his level to 60 without them and then +20 (Lv. 80) using the Scrolls. So the total amount necessary to raise his Light points up to 100 with that method is 3,800.

If I knew this when I played around ver. 1.5, I would have stocked the Scrolls as many as possible because I am not such a player as spending tremendous money on Gallery of Dreams... It takes about 7 minutes for me to get 50 mil. EXP (equal to one High Class Scroll) under the JP ver. 2.2.10 circumstance. This means that over 443 hours are necessary to raise his level from 60 to 80 for 100 times.

*There are several other unique features for him, which are not necessarily relevant to the subject here.
