Musashi's hit count up skill is something I've always wanted on some other servants, so it being exclusive to her makes me a little sad. It's such a simple yet terrifyingly effective improvement to any servant.
Well everything else didn't suprised me much when they first came out. I always had a feeling something like that will be added one day. The only thing that interest's me is eternal sleep. Cause it's the first time that a playable unit got an unblockable skill even if it has a heavy debuff with it. It is good for supports like Shakespeare who have a buster np. And I kinda have a liking to it's lore too.
