Please make it clear like [Use Dups "only" or Soul Cube] not [6 Star with a same class]
Seems clear enough to me
yeah, I tried it too
Clearly not clear if you are not reading dumb...
you must required a Same Pass Hero SR or Other SR Type magic
the exp gained when it is not a dupe (same character) is halved vs if dupe but thats how it works even before major update - you can use any SR of the same class
