I cannot beat Abyssal Road because MN Seere does infinite damage with any hit she lands.

Damage = difficulty and its eternal impact on game design, Master Ninja on NG4 might be one of the worst difficulty options i've ever seen in a game, I got the 100% on this game, so I know what im talking about, and I can confidently say that MN teaches you to play the game like a scrub if you don't want to get one-shotted by some unreadable or unreactable bullshit, although on the earlier games most of MN is you spamming OLUTs, the boss fights wasn't a race against you getting hit ONCE.

Genuinely the worst aspect of NG4.
