From this thread.
I have too many contingencies to die. I've seen others die to blatant stupidity and dumb luck though.
I thought it meant the spell, or this feat that Solo posted.
Due to my inexperience with playing D&D I haven't got a clue what works and what doesn't. Also I didn't get the last sentence, I am not a native speaker.
edit: Wow ok, I just realised that thread was nearly 3 years old
Fuck, my reply to you got deleted somehow. Let's try this again.
That character had:
Decent HP for a mage, 150 at 15 or so.
AC actually high enough to matter, mid to high 50s.
Saves low to mid 20s across the board + Ruin Delver's for +11.
A decent, but not great Init.
GMI on demand.
Save or dies/loses, mid 30s DC.
Craft Contingent Spell, Auto Life, stat guards, some other things.
For one feat, a near 300 HP beatstick who could take hits in her place (gasp, a beatstick who can actually protect others), debuff enemies with negative levels (10 a round), and do decent damage, about 200 or so.
End result was a character who went full levels without losing a single HP when it was easy and was either the only one to not die, or the last to die when it got very hard. I forget if that auto life ever actually got used. It wasn't at the time I wrote that.
