Hedge Maze
The Hedge Maze is accessible from Floors 3-5. It leads to the Hive. It has a 50% chance of appearing each game.
There are a few tricks to navigating the maze. A Revealing Essence potion will come in handy. Some of the hedges are destructible but you can only burn them and not cut through them. The maze is not particularly large and you can usually find the Hive entrance quickly. Besides a statue and a couple Bees there is nothing else to find on this branch.
