Man, I jus reached floor 101 and died. All the bosses were so slow(except credo) and i was easily able to detect when they are open but this guy kept coming at me. I detected a couple of openings but by then I died....Hilarious.
Anyways, I came here to say 2 blitz ain't that much of a problem beyond stage 80(Atleast with nero). However after killing Ist blitz, 2nd blitz goes into DT. Even after charge-shot-ing blue rose nearly 4 to 5 times, he was still shielded. As always, I went near him and DTed and then he lost the shield. Then buster 4 times and adios Blitz.
