I remember playing a dual-wielding 8th level ranger in a tunnel being mobbed by 100s of bugs with average ac and missing something like 12 attacks in a row. I just wanted to burn my dice and character sheet and start overMy most significant case of unlikely dice luck was when I built an Elven Accuracy based ranged fighter, brought her in to play for the first time, got myself perfectly situated, and, in my first ever roll for the character, attacked from averaged vvvconcealed position with an advantage...
And rolled a triple natural 1.
