Playing a dustform Warforged Artificer (don't ask) in E6. If I take a critical hit from a bludgeoning weapon I have to make a will save of 10+damage or die instantly.
The good news: We are using the vitality and wound point system, meaning crits don't do extra damage.
The bad news: Will saves are hard to pump in E6.
The terrible: Although warforged can become immune to crits, I don't qualify for the feat because of my pathetic BAB.
My best solution so far: STAY AWAY FROM THE BAD GUYS.
