Once you open the door with the Shard of the Rain, you will be able to progress to the next area, which is called the Industrial Complex. The Industrial Complex is a large and dangerous area, so be prepared. There are many enemies there, including the Rain Frogs, the Shaded Citadel Guards, and the Industrial Complex Workers.

You do not need to collect anything else before proceeding to the Industrial Complex. However, there are a few things that you may want to consider collecting before you go:

* The **Scavenger's Cape:** This cape will allow you to disguise yourself as a Scavenger, which will allow you to move through the Industrial Complex more easily without being attacked.
* The **Spearmaster's Armor:** This armor will protect you from the attacks of the Industrial Complex Workers.
* The **Spearmaster's Spear:** This spear will allow you to attack the Industrial Complex Workers more effectively.

You can find all of these items in the Rainy Cavern.

**Tips for surviving the Industrial Complex:**

* Be careful of the Rain Frogs. They are very dangerous and can kill you quickly.
* Be careful of the Shaded Citadel Guards. They are also very dangerous and can kill you quickly.
* Be careful of the Industrial Complex Workers. They are not as dangerous as the Rain Frogs or the Shaded Citadel Guards, but they can still kill you if you are not careful.
* Use the Scavenger's Cape to disguise yourself as a Scavenger. This will allow you to move through the Industrial Complex more easily without being attacked.
* Use the Spearmaster's Armor to protect yourself from the attacks of the Industrial Complex Workers.
* Use the Spearmaster's Spear to attack the Industrial Complex Workers more effectively.

I hope this helps!
