Hmm...
Long time ago, back in 2E rules, I was playing an elven ranger. The rest of the party was busy with a problem in one room of an underground complex. I had little I could do about that problem, so I moved into the next room to cover the entry.
Down the hall came 8 drow in a double column. Four fighters ahead of 4 priests.
From what we had seen before in the dungeon, these would have toasted the party had they caught us unawares. If I try to call out, or retreat, I will be noticed and toasted right quick, as they'll concentrate on me. If I don't do something, within seconds, everyone will be toasted...
So, I make like a dual-sword wielding kzinti - I scream and leap...
The other players moan, realizing that my delaying the enemy probably saves their butts, but they'll be scraping me off the floor when they do arrive....
...and I manage to get surprise. A full two rounds of surprise. I manage to get multiple criticals in the next three rounds of attacks - my dice refuse to roll anything below a 17 on a to-hit. By the time the party arrives, two fighters and two priests are dead. Two other fighters were wounded, and I was working on the remaining two priests....
It was a darned good day to be me, let me tell you...
[edit: Oh, and I still have those dice. They're my babies
