To upgrade the "Hand of Void" and "Glyphic Language" to the next level required 60 XP, and now Arthur had 82 XP, which meant he had 22 XP to use freely.
22 XP was more than enough for him to upgrade all the skills in his "Auxiliary Skill Bar" not just once over.
However, considering the potential issues he might encounter at Oakwood Manor, Arthur prioritized upgrading his "Eagle Eye" and "Insight" by two levels each.
In the end, he still had 1 XP left over, which Arthur decided to invest in "Painting."
The auxiliary skills were upgraded as follows—
"Riding Lv2 (0/5)," "Intimidation Lv3 (0/10)," "Bluff Lv3 (0/10)," "Eagle Eye Lv3 (0/10)," "Insight Lv3 (0/10)"
...
Besides that, the general skill "Painting" was upgraded to Lv2
Just like when combat skills were improved, the synchronization of knowledge and body both completed in a short time.
Even with a large number of skills, it hadn't caused Arthur any discomfort.
