The skeleton that attacked me first night was a pain. Thought it might have just been bad luck RNG putting a skeleton spawn right next to the stone ring in the meadows where you spawn in the game.
Then the crypts I found just in the black forest both had one star green skeletons and the one with the two star sword skeleton was a bit much for my early equipment / food / stamina. That is when I decided the game was not for me. I guess they made some changes the next day to the update. But good luck.
