Bell has level 5 <stats> and is a level 4 who can fight as a level 6.
This was a translated tweet I found.
Might as well make Bell a level 10 at this point
I thought it was an interesting find. Either way, it explains why he injured Hedin during their most recent fight even though Hedin was holding back.
So, Bell at this point should be able to solo even a Gulliver brother.
What do you think?
