Accept help from secretive voices in your head on the vague condition that you will "let yourself be open to their power".
One of my PCs has more or less done this...
Give your DM a such a long, detailed pain-filled backhistory of your character that he knows EXACTLY what buttons to push to drive them over the deep end.
Did this last week when I spectacularly killed off an NPC who has been there since day 1 of the campaign, two years ago, and is married to one of the PCs. And then the raise attempt failed...
Mistake 1: picking a fight with a Baernaloth
Mistake 2: picking a fight with a Baernaloth named 'The Flesh Sculptor'
Mistake 3: doing so while standing in the middle of Citadel Cavitius while it's under seige by 2 splinter sects of the Doomguard and a Ship of Chaos.
Pull up an arcanoloth's robe in order to resolve the debate you and a friend have been having about whether or not they have tails.
Oh, it's the presence of a 'tail' that they're debating. There's that little 'hermaphrodite' line in 'Faces of Evil' that's gotten more worried consideration from my players, and more snide jokes. And one of the PCs is actually -dating- A'kin...
Insult Shemeshka's fashion sense and make lewd comments about potential reasons why A'kin doesn't like her.
They've done this, oh how they've done this, and she's gotten back at them in some non obvious ways.
Shake hands with a fiend while wearing lots of silver jewelry, then laugh at them when they flinch.
They've done this too, and they habitually pay any fiend in only silver.
A few of my own:
Strike a deal, on your own, with a NE insane member of the Incanterium who has been slowly starving over centuries inside one of the mazes of the The Lady of Pain. Do this when the entire rest of your party strikes a deal with the LE lich who has been in a stalmate with her the past 10 or so centuries.
Sit there and say, "You know... we don't have to fight." as the magic eating sorceress eyes you like a prime rib and casts haste on herself. You don't cast haste to bargain, she wasn't the micro machine man.
