I’m more curious to know if anyone has tried it and to what degree of success?
I was in my public pool earlier and I dived to the bottom and thought this would be a truly surreal place to do an evocation. Maybe not under water unless you can hold your breath or had a scuba/snorkel mask, could be floating, or sitting in a stream.
Could be an effective means of calling to the water beasties. Unfortunately, I only have immediate access to a public pool and a tiny bathtub just won’t do for me to try this.
