If you take these things into a cave, the only thing that will aggro on them is a megalosaurus. I took Tickle Fingers on a chitin run, and the only thing after to eat my tail was nothing. I wandered into that cave like it’s a daily thing. Of course I had centipedes, snakes, Scorpions, and spiders after my blood because I impaled some of their friends with my fingers of doom. Perfect for chitin runs for caves
