In the tomb of horrors, there is a door that summons a monster to attack the players if the players stab the door. This is apparently something that not only happens in Gary Gygax's campaigns, but happens often enough that he encoded it into one of the most famous dungeons of all time.
It used to be a common strategy to poke or stab things to see what is real and what wants to hurt you, I think stranger things even touched on it a bit.
Yeah ten foot poles were standard gear for a reason.
I don't really like traps too much as a DM, it seems too easy to make a lethal trap (at least in a fantasy setting) and why would the makers bother with a non-lethal one?
It was probably even worse in 1st Edition, when characters could buy experience with gold and when they said "adventurer" it was understood to also mean "mercenary"
I cant help but feel like they've lost their appeal over the years though. When you can point at a monster and say "oh thats a Shoggoth! it has x stats and y HP and has z special ability" on sight, the fear of unknown that's so essential to lovecraft is gone and its just a funky slime.
Many games can turn into Surprise, It's Call Of Cthulu.
Which seems appropriate. Few of Lovecraft's protagonists set out to discover untold horrors. They're investigating a murder, or searching for a missing person, or seeking magical power. They don't know what genre of story they're in.
