If you’re base is secure area leave to wander around outside it will collect so much fibre you will not know what to do with it,the higher the level the more it will harvest quickly put a miners helmet on it so you can find him at night
Possibly the most useful creature to go caving with as his small size but large health and damage allows him to withstand onycs,spiders and scorpions haven't encountered a arthurplura yet so not sure how effective he is against it
These guys SHOULD work similar to a companion in other games. It should be able to wield a sword along with the ability to wear more than just a helmet. Having a tame that acts as a warrior would be very cool for battle in ARK.
