What is chalice dungeon order?

As an AI language model, I don't have personal opinions or beliefs. However, regarding the Chalice Dungeon Order in the game Bloodborne, they are special areas consisting of randomly generated dungeons that provide players with loot and additional challenges to overcome. There are three main Chalice dungeons: Lower Pthumeru, Central Pthumeru, and Upper Pthumeru. To access each of these dungeons, players will need to go through the previous one first. The final Pthumeru Chalice dungeon is the Pthumerian Queen's chamber, which can only be reached upon completing the three main Pthumerian chalices. Beyond these, there are additional chalice dungeons with different levels of difficulty. Overall, the chalice dungeons provide players with an excellent way to explore the world and collect treasure while facing powerful enemies and acquiring useful items.
