Improving crit range on bludgeoning weapon [3.5e]

[Scarey Nerd]

As the title suggests, I'm looking for feats/magical enhancements etc that can improve the crit range on a bludgeoning weapon. My Dwarf Wizard/Fighter/Runesmith has the Greathorn Minotaur Hammer from MMIV, and I want to make it ridiculous. even just getting it down to 17-20/x4 would be fantastic.

Well there's the Improved Critical feat. There's also class features from Disciple of Dispater from BoVD that double crit range, but I don't recall if it stacks with Improved Critical or not, or even if it works on Bludgeoning weapons. Improved Critical does what you're looking for though.

Third Party allowed?

I'm not entirely sure what you mean by Third Party, but I'm allowed pretty much any source book or dragon magazine, no homebrew or anything else. I've seen improved critical, but you need a BAB of +8 to get it, and I'm looking for stuff before then.

Impact enhancement, from MIC. It's Keen for bludgeoning weapons.

"third party" means d20 material not published by WotC.

:smallbiggrin: Exactly what I was looking for, thank you. Shame that most critical enhancing things stipulate that they can't stack, but never mind.
