The previous owner of my current nutaku acc seems couldnt do the very last map (2*) and the one with black oni rushing in (1*) on the original event. Latter handled ez with despara saw, watching her freezing the shit out of the fucker was satistifying as for the former, well, how could i know that shining black oni was this stronk <_< gotta spam deine+sybilla next time (i should stop being a lazy ass and level that pippin...)
Looking at enemy stats, obviously event tells us to spam magic damage.
