I've been researching the mechanics of the stealth skill, and I have a fair amount of uncertainty about how the rules work. I do society play, so this is frustrating, because it's hard to have confidence that a build will function consistently with different GM's. So I suggest the following:
In the skill description, the Stealth functions of "Sneaking" (meaning avoiding detection while taking actions) and "Hiding" (meaning avoiding detection by obscuring location) could be divided into distinct sections.
It's challenging to understand how factors like cover vs total cover, invisibility, scent, light level, ambient noise, etc. affect these two separate functions when they're lumped together.
On the other hand, I definitely like getting them both by training up a single skill, so I'm not suggesting separate skills. But it would be great if Stealth could be more like Acrobatics, and the way leaping and tumbling are separated there.
