These little guys span everywhere they could be irritating, at least when there is more than one. There base dmg will tickle you they sometimes don’t attack they have very little health. They spawn in very large clusters.
nueral husk, if you get one if these you can convert them into an equipment that you can use like a glider, so it saves you from fall damage and makes you glide a bit. sadly to make this glider you need both the neural husk and to buy the engram of the glider from the shop using ambers.
