Thats the beauty of this game. When you think you have seen it all, you find something new. The game is a Masterpiece. I shudder at the thought of Nintendo releasing the game back in 2015 like they promised. A bit of patience pays off.
Use a bomb to kill a stalkoblin on horse back. The head flies into the air and gets destroyed when it hits the ground. I only first noticed that while doing the trial of the sword.
