Minecraft wiki entry for Defeating_a_woodland_mansion, associated text: Since the journey to the mansion is extremely long, chances are you’ll discover new places along the way, some of which contain extra loot. Do explore them before continuing on your journey as you might be able to stock up on supplies for your upcoming raid. Blacksmiths in villages and temples are among the more useful structures you’ll find. You can also find many other biomes and rare structures. If you find a ocean monument, keep the coordinates of it because ocean monuments require different equipment.
