I didn't wrote about supersonic, just in case - never faced unintentional battle. But it's really fun.
Only once there were a problem where followers choose a path near one-shot air totem.
That wasn't a big problem. so I just re-load.

And as I sad - I won the arena. So I should be "the one" - but no.
Underground lady only told me that there is no vacant slot to fight - come back tomorrow. Sight =(

It's twice sadly, just in case I found a lots of magic source, but can't use them =\
