I encountered my first one today upon turning on my PS4 I spawned at my base and suddenly hear that some beast was trying to demolish it I thought I was getting raided so I opened my little window from my 2nd floor and peeked out when suddenly this big bird with claws struck me in the face blood was oozing but I held my ground made 100 stone arrows left through my back door sprinted as fast I could I even lost my boots in the process them jumped into the river then got into land, I approached the beast slowly and started fireing my arrows luckily it was distracted by my base idk why so I spent about 80 arrows till I took him down it gave me about 70 meat 200 leather, however my stone base was almost destroyed with about 900points left to destruction
