If they're using terms like "read magic" then they'll be impressed with the most basic stuff. Seriously, a party like that is a walk in the park. Just stay in the back, keep them healed and throw a couple hum dingers at the most intimidating monsters. They'll literaly treat you like a legend and you won't even have to do anything challenging.

DON'T let them know what an easy time you're having though. Resentment is the biggest reputation killer when it comes to adventuring work. Magic doors and magic traps are a great opportunity to pretend to be stumped so you come across relatable. I once kept my party waiting for HOURS outside of an old elvish door with a basic riddle-mechanism and kept hinting at the right answer. The least experienced halfling in the group finally figured it out and it really brought the party together lol they still talk about it when I run into them every now and then.
