Revenge has always been the prime motivator for ultra cool PC's that kick arse.
Play a cleric, I think one of the largest amounts of hate I ever got was playing a cleric. Wasnt even a very fancy cleric or optimised and as another BBEG is down to its last 10hps, it was hilarous to hear the scream from the other side of the table....
"JUST GODDAMN DIE DAMN CLERIC!!!"
to which the reply was "Flamestrike"
So, I retired as the GM was in tears every time I got cranky and nuked all his 'lil babies' into ash, the walking med-kit-flamestrike cleric ascended to play with the other clerics up there in the heavens.
Which left us with no cleric.
hmmmm I thought, may as well make this bastard suffer, I really liked that cleric and so did everyone else because it actually healed them when they need it.
Gathering around the other think tank of gamer nerds and uber munchkins in the office we got to thinking, how do we break this GM? He made me retire a character I loved and he was being a ****wit about the whole thing, I mean, all it did was nuke and heal

Cleric archer? nah, too blatant.
Paladin, nah, already got one.
fighter, been there done that.
rogue, not what we need at the moment.
So we crunched and crunched and came up with a rather innocent looking enough build. Elf, figher-rogue and tacked on a few levels of Order of the bow initiate. I'd always wanted to play an archer in 1E-2E but they sucked so bad you wouldnt pay $2 for it down at a knocking shop.
I think I worked out that it was doing 1D8+10+9D6 a shot at a rate of 6 shots a round.
We didnt need healing
It worked.
Broke him bad, bad in a way that cuts a man right to his soul deep down inside...
( I mean, it was either that or a Kobold on a dire weasel)
