Monsters of this sort can be found in any size but Large ones are typical of those that might be encountered in mountainous areas. \n'b' Ophiolites\xe2\x80\x99 physical characteristics make it easy for them to go unseen in rocky terrain, even if they are not actively trying to do so. They can burrow through anything up to the consistency of rocky earth but not through anything as resilient as bedrock and \xe2\x80\x94 in that they are very sensitive to loud sounds like thunder \xe2\x80\x94 they often use this capability to lurk just below the protective surface of the ground. \n'b' Ophiolites are not particularly aggressive but are sensitive to vibrations and hate being unexpectedly touched or stepped on. They will typically respond by lashing out at whatever has upset them and attacking it with their razor-sharp fangs and powerful mineral poison. \n'b' Their rock-hard hides make them much harder to damage than normal creatures. \n'b' An Ophiolite\xe2\x80\x99s brain, heart, liver, and kidneys are composed of gem-quality serpentine, and if a character knows to look for these and is able to successfully harvest them they will typically be worth about 400 gp altogether for a Large creature of this sort.'
