i am a midnight blade lvl 37 on server 303 shikagami dance, i have cleared the survival trial 5 times in a row till the 12th stage and i thought by now i should be able to sweep some lvls. however, i can't and i have posted this as a normal post before just to see if i was just missing something but it seems that i didnt. someone advised me to ask customer service and i just want to know if this is a bug or is there a requirement i am not meeting.
