You can use a dive well to get into a basement? Do you have to use debug commands, or do they automatically connect if you have two of them?
Yes you need to use he buydebug mode, then you need to name each well, and make them ubawarp and put the name of the other well you want to warp to and vise versa, then explore and you get a measage do you want to go threw a tunnel and it will work.
YOu need to use the Ctrl+Shift left click on the well to get the options to set it.
You need more then one well tomake it work, one well outside and the other well inside.
Yes you do get puddles and you drip like crazy threw out the basement.
