Homebrew Cave troll Species Details

Cave trolls live in underground caves some in deep caves hundreds of metres underground while some live closer to the surface. With stone skin they essentially inpenetratable. Those who live in the deeper caves have developed with no eyes instead using the crystals that grow on them to send vibrations like echo-location allowing them to navigate their homes. To help with burrowing Cave Trolls have developed the ability to mould the earth around them. Due to little to no creatures that cause harm to them at such levels deep Cave Trolls have little to no self preservation and fight or flight skills.
