I am looking to use life bubble in both Pathfinder and Starfinder. I'm trying to figure out a way for life bubble to contain salt water.
The description of Life Bubble reads, in part:
You surround the touched creatures with a constant and moveable 1-inch shell of tolerable living conditions. This shell enables the subjects to breathe freely, even underwater or in a vacuum, as well as making them immune to harmful gases and vapors, including inhaled diseases and poisons...
Life Bubble creates a habitable and tolerable living environment for the target. It doesn't matter what that creature needs, it gets it. If the target can only live in salt water than it will be filled with salt water, etc.
The Bubble can't be used offensively, because only those things that make the environment tolerable for the creature are retained within it.
