"I need anything but a '1'."
Of course, the outcome of the roll will be a '1'!
In the 3.0 campaign I play in I have a Cleric/Brb/Warpriest of Tempus. With a Fort Save up in the middle 20's (can go upt o hightwenties when raging). He also has a really high AC.
We're facing a Naga with alot of spellcasting ability and 3.0 Haste. The other PCs are having trouble hitting the damn thing, so I decide to walk past him and get into flanking position, in order to give the Other memebers a better chance. This of course will provoke an AoO. By the way, we use the rule that a nat 20--->30 and a nat1--->-10
DM: " That move will provoke an AoO, sure you want to do it"
Me: (confident grin since the DM had missed all of his last 6 attacks) " Davon heroically rolls through the reach of the foul beast in order to trap him."
DM: " Ok....the Naga attacks with it's posionous tail"
Me: (Still Grinning)
DM: "...roling...a 20...Critical Threat!! (evil glint in his eyes)..."
Me: "No problem ...there's no way you're confirming..."
DM:"...another 20...let me see, that's a natural weapon....x2..18 hps.roll for Fort Save DC 17"
Me: (Grin still going strong) " No problem...with my +26 fort asve I'll only miss on a 1......roll a 1."
...... 1...... (grin slips, panic begins to set in).
DM: " OK the naga does 3d8 Con damage...that's a 8 + 7 + 4 = 19. What's your Constitution like now?"
Me

looking at the big fat 18 under Constitution on my Character Sheet) "..... "
DM: " Come on, how's Davon doing"
Me "...."
DM: (throwing me a bone) "well since the poison is happening during your action, and it isn't instantenous, I guess you have time to finish your action.
Me: "....."
Dm: "Well...:"
Me: " What the .... how did that happen"
DM: "we'ew waiting..."
Me " Well If I'm going down I'll go down swinging....Activate Rage..that gives me a +25 to hit...roll...1"
DM: "hehehe"
Other Player :" Hey doesn't rage raise your Con..."
Me: "....YES!!!"
I lucked into that one, but the DM never forgave himself for giving me that extra shot.
