First NM: Bigmouth Billy, before I even had a sub. Didn't know what the hell "Impossible to guage" meant, so I left him alone lol. A few levels later, second NM was the Sea Horror, didn't understand sound aggrro and was one shotted. And the third NM I ever saw, and the first I ever actively camped, Spiny Spipi, camped, claimed, and dropped first try. Sadly, I have never had that kind of luck NM camping since.
