The overall proficiency in all abilities has increased by over 2000. Reiger did not expect such rapid growth even after reaching Lv.9, indicating how many powerful abyssal creatures Reiger encountered along the way; otherwise, he wouldn't have been able to gain so much experience.
Of course, some of this experience comes from the two battles Reiger fought after arriving in Source World; one confrontation with the Abyss Demon Lord in Orus and another against all the strong entities and Night Spirit Aggregates outside the Karedohart Empire's outpost zone.
Probably, that's why the level of the development ability 'Unlimited' has increased?
Ultimately, Reiger was restricted by the barriers deployed by the Dark Relief Center in that battle, which triggered the development ability 'Unlimited.'
As for the development ability 'Curse Binding' that was just obtained, Reiger wasn't surprised by its increase.
