I once got crushed to death. By a pike. That I was throwing.

One time I got curious and
kissed the dying mind flayer in the nautiloid wreckage

I also called the bluff of
Vlaakith, turns out she wasn't lying

I've died several times because I forget that holding a torch (Or burning weapon like the Everburn Blade) will automatically ignite surfaces you walk on which often gives a surprise in
the Zhentarim Hideout. Also in the Goblin Camp behind the trader where the barrels of Smokepowder and Oil are.
