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: Bad Street Brawler
Demonic Spiders: The Breakdancers. They deal three damage just by moving through you, they can't be knocked out of their dance, and they usually change direction if you jump over them, making their attacks incredibly hard to avoid.
