Exteme, fun sub(per)versions of the rules

[radmod]

I'm curious as to some extreme, fun subversions/perversions of the rules that people have seen and I hope people will share.

My favorite comes from 1e. (Hopefully I remember how it worked)
Wish caused the spellcaster a loss of CON. Wish also allowed you to increase an ability score by 1 pt up to 16, and 1/10th of a point beyond.
We were playing evil characters in a world where our home base was a huge city with millions of people.
We would snatch and grab bums off the street (no one cared if they disappeared). Then we would magic jar into their bodies and cast a wish, wishing that our original bodies would have an increased ability score. Since the wish affected the spellcaster's body (the bum) we were able to increase our stats without losing anything.

Now this was probably a perversion of the rules, but it was allowed primarily because the DM also played a character and he wanted the stat increases. What can I say, we were young; even if it worked that way now, as a DM, I would have problems with it and come up with ways to thwart it.

EDIT: I suddenly remembered that some kind of Permanency was also required.

3.0 potions of shield. Mix in together: A 1st level spell, Brew Potion feat. Voilà, for the price of dirt cheap, instant +7 to AC that stacks on the heavy armor to the melee dude.

Suddenly melee-type characters become obnoxiously unhitable if they get access to a supply of these things especially through a magic mart environment seemingly promoted by Core assumptions. Shove a few into that Heward's haversack, and you are set for many levels worth of BBEG's.

This abuse is why 3.5 nerfed the classic spell down a few notches.

PAO golems into beads. String beads up around neck. Next time some idiot tries to put you in an AMF, he gets to deal with golems since the AMF suppresses PAO.

@ The OP: That is possibly the silliest story of overt powergaming I've heard all week. Bravo! I think?

To continue the story: I wish you could have been around to look at Wizards' original character optimization board. The subversions, perversions, and all-around twisting of the rules was so incredible it sometimes made my eyes pop.
