The reward for completing a quest in the Restricted Section of the library was plus one to a specific skill's level, which meant the higher a skill's level, the more value the reward would yield.
Currently, among Albert's skills, the highest was level 5 Wizard Blood. The second highest was level 4 Occlumency, while the rest were only level 3, level 2, or level 1.
After thinking about it seriously for three seconds, Albert finally claimed the quest reward, elevating Wizard Blood to level six. Although improving his bloodline did not do much for his immediate combat strength, Albert upgraded the skill anyway.
