Rock Trolls are immense creatures with durable hides like stone. Like their Troll cousins they can regenerate and severing a limb merely results in battling a second troll in mere moments. However, unlike their cousins they are NOT vulnerable to fire. they are however vulnerable to water-based attacks which can be used to dissolve them. The amount of damage greatly depends on the type and quantity of water being used. For instance a simple child's squirt gun would inflict damage equal to a simple firearm but a a weapon as powerful as a fire-hydrant would be much more effective killing the creature in mere moments. Rock Trolls can be controlled and tamed (relatively speaking) but do not make good pets and when found tamed they are usually used in a gladiator capacity as an execution method. Rock Trolls give birth only once in their lifetime via mitosis the newer offspring being half the size of it's parent. Rock Troll diet consists of sand stone and rusted metals these permeate their skin granting them a natural camouflage rating of 90% when not moving. Rock Trolls do not register on thermal or life scans making it nearly impossible for them to be detected on any given planet so explorers are advised to be cautious when exploring planets which would be suitable for Rock trolls to inhabit.
