Shattering weapons on a creature

[BOZ]

hi! i am working on a monster whose hide is so thick and hard (5 feet of rock) like a boulder that weapons may shatter on impact. maybe only slashing and piercing weapons. the creature has DR 20/bludgeoning. i'm wondering if there are any existing mechanics to do this, or if there is a way to tweak existing mechanics to do this.

this is for a conversion of the stone-eater/horgar that we are working on here: http://65.127.163.19/showthread.php?t=66584&goto=lastpost

How about simply, if the weapon doesn't get through the DR it must make a Fortitude save DC 15 (or automatically for non-magical or non-special material weapons)?

Or you could limit it to those weapons that do half or less damage than the DR (10 or less).

Just a couple of ideas.

The Rukanyr in Fiend Folio has a nearly similar ability tied to its grinding armor plates.

How about basing it the Rust Monster's ability?

Rust (Ex): A rust monster that makes a successful touch attack with its antennae causes the target metal to corrode, falling to pieces and becoming useless immediately. The touch can destroy up to a 10-foot cube of metal instantly. Magic armor and weapons, and other magic items made of metal, must succeed on a DC 17 Reflex save or be dissolved. The save DC is Constitution-based and includes a +4 racial bonus.

Just change it so that it happens when the monster is hit or when it tries to sunder a weapon. Call it "Diamond Skin", or something.
