Feng Shui Questions

I'm struggling with this-- my rooms are all auspicious but only because I'm careful to work with one element at a time. Always a stone or a wood. I've never had a room that was very auspicious.

Things were going okay but now I need to contain the mysterious cavern and I'm forced to build with multiple elements at once, including water. I've tried building water-element rooms for grass-cultivators before but they were always too cold, I learned they didnt seem to care what element the room was unless it was for meditation/ breakthroughs so now I just build with wood or stone. It seems like whatever I try in the room with the cave the feng shui is neutral I don't know what I'm doing wrong

Im looking for advice on building with water feng shui and the mysterious cave in particular (I got the statue from the ancient cultivator but its fire type and the cave is water and it doesnt seem to make a difference) Im kind of at a loss and people are starting to die while I deal with it so I had to just stop the game. I tried testing things in build mode but the animals are immune to weather damamge there (?) and destroy everything

The statue doesn't matter where it's placed as long as it's in a display in a room with the cavern to automatically turn the area into a fully auspicious area. Be sure to add a Feng Shui structure.

Since the mysterious cavern is a WATER element based Feng Shui SUPPORT it can feed WOOD based Feng Shui Structures. One way is to just plop down a WOOD Water Vat next to the cave and add some WATER element based SUPPORTS like Lighting Decorations next or at least 2 squares within the Water Vat's range to make the Water Vat have Very Auspicious Status, rendering the room Very Auspicious. Make sure the flooring is WATER based as well as this contributes to Feng Shui.

The only problem with relying on the Water Vat method is that whenever a Qi based weather phenomenon happens, it can tank the Feng Shui slightly or drastically so keep that in mind.

Here's an example room:

Materials around the WOOD water vat is all WATER based element supports, which is an element that feeds wood based Feng Shui structures, such as the example water vat.

And if you dont want anyone to use the water vat, just build a wall in front of the door of the room.

Oooh I see I thought the cave was functioning as a feng shui node but its not, as soon as I put a water vat in it went auspicious-- thank you very much!

The room is very auspicious but its still getting more mad is that right? it went from not satisfactory: 16 to 24

Also how do I sacrifice people to it? just out of curiosity

When the room is Very Auspicious, there is practically no chance of it getting angry. Any dissatisfaction it has gained will remain. It is not recommended to feed the cave as the creature gets stronger that way when you release it. There's usually an event that pops up whenever it asks for sacrifices or you decide to make a wish.

There is a certain setting in Immortal mode where the creature will eventually come out and battle you. Suppression under this setting only lasts for about 500 days when the room is set to Very Auspicious.
