So, I'm playing a character who can deal substantial damage for its level with a single weapon hit, using warmage edge, arcane channeling and bunch of other loopholes.
My DM recently mentioned that he'd like to give me a house homebrew item or ability that doubles my damage in a single strike once a day, but if I miss, I deal that damage to myself. I can deal 50-80 damage normally, and my HP is 70, so I guess you can see the problem.
The damage is basically as follows:
Bastard sword - 1d10+3 physical
Burning sword spell - 1d6+6 fire
Blade of force reserve - 3+6 force
1st spell arcane channeled - 8d6+6 electricity or 7d6+6 fire
2nd spell stored - 8d6 electricity or 7d6 fire
Knowing my DM, simple true strike spell tricks won't cut it, he'll find a way around that, like cruel disappointment spell or something.
Is there a feat, spell, or item that I can use to negate -or at least survive- this damage if I happen to hit myself with it?
We're using d&d 3.5, I have the craft wondrous items feat already, and we can use any written source, including dragon magazines, just not homebrew.
