Hi veteran ironmen!

I always play games on the hardest difficulty and have been playing an ironman rogue in exiled kigdoms. I'm absolutely loving it and every death is teaching me something new.
After failing around 6-7 times i was finally in a really good groove, reached level 8 and feeling confident. Then i spoke to a shady traveler (as i have many times before) and BOOM he stabs me with a black dagger for 95 damage and i die.
I am fine with this as i have now learnt something new, but i cannot find any information about unexpected deaths or things to look out for on ironman!! Since i have never played the game before i don't know what to expect, which adds to the fun, but i don't like dying when there is no way of knowing it would happen. So before i start my next attempt, what are the unexpected deaths/damage that i need to look out for (like getting stabbed by a shady traveler)??

TLDR: playing on ironman, what unexpected deaths or serious damage that cannot be foreseen do i need to look out for?
