To be fair, I didn’t really focus on the biggest annoyance I’ve had with spaces in the file name: going between terminals and the GUI, most filenames you can copy and paste with wild abandon, but filenames with spaces always require special care, sometimes stripping the auto completed escaped space from file names from the terminal, or quoting or escaping the space when taking one from the GUI.
This is actually really strong for a max level artificer as they get a +1 to all saves for each attunement
