@scotthertzbergdo you have a recommendation on handling “monster knowledge checks” in 5e? Wondering if DC 10+CR or something would work. 10+CR is reasonable – with the caveat that I'd allow it only for creatures that could reasonably be learned about

@scotthertzberg In my games, I don't allow checks for weird creatures that a PC couldn't have possibly heard about.

@scotthertzbergmakes sense – thinking about how PCs might know about a skeletons vulnerability to bludgeoning or something Yeah – i like to use it for stuff you might hear about in a tavern or from veteran adventurers
