Hit : 13 (2d8 + 4) slashing damage. \n'b'\n'b' ABOUT \n'b' Untold ages ago, the pechs served forgotten masters in the deepest caverns of the world. In time, their masters moved on, leaving the pechs bereft of  guidance . Some sought refuge in seemingly safer tunnels nearer the surface. The unspeakable horrors they encountered there transformed them into derros over the course of several generations. Those pechs that stayed close to their ancestral caverns survive to this day, though in such small numbers and in such isolation that few of the surface world know of their existence. The typical pech stands only 3-1/2 feet tall, but its dense flesh gives it a weight of 100 pounds. \n'b'  Stonecutters . Pechs are skilled miners and stonemasons and are at times employed or enslaved as such by other subterranean races. They have learned to  hide  the entrances to their lairs most carefully, blending their narrow entranceways into the living rock such that they can only be seen from exactly the right angle. When interlopers do find a pech\xe2\x80\x99s lair, they are met with open arms, friendly advice, and a firm insistence that the pech is to be left alone.'
