Just in case, I had always defended with the sturdiest part of my shield, and I hadn't received a single injury up until now.
So this is my very first time experiencing damage. That's all there is to it.
I watched the Whetstone Shield's auto-polishing at work. It really was quite a convenient shield, one that I always used.
The polishing time period was 8 hours. There'll be no effect if I pulled any weapons out beforehand.
The only drawback was that while in use, my SP won't recover since I'll be continuously drained.
Ah, speaking of which, I guess I should try utilizing the other abilities in my skill set...
“Air Strike Shield!”
