These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Sword Of The Samurai
Demonic Spiders: Arquebus enemies in a melee. Unlike archers, whose arrows travel slowly enough to dodge, bullets travel very quickly. And since one hit will slow you to a crawl, you'll usually suffer a second, fatal hit right afterwards.
Goddamned Bats: Any rival with rock-bottom honor. They have nothing to lose, and so they will endlessly try to assassinate you and kidnap your family. This means that if you stay home, you'll have to do lots of swordfights, and if you leave home, you'll lose a family member and end up doing some Melees to get them back. It's not that they're terribly difficult to defeat, but it gets annoying very quickly.
