I'm playing hide and seek with my friends. I hide behind trees, rocks, or in a building.
You don't see me because I have a really hot spot under a tree line, behind a rock in tall grass, right? Ollie ollie oxen free, or however that's spelt.
So, the astral plane glows with the energy of life.
Just because you're astrally perceiving doesn't mean you can see through walls.
So, here we are, having a discussion about what have you, and you're astrally perceiving. I'm in front of you, I'm a glowing blob o' aura, right? Hard to miss, even.
So, I goto my hideyhole in all my glowing blob 'o aura glory, right?
I'm under trees, they're alive. They count as cover.
I'm behind a rock, its inert and non living, but it blocks you from seeing me.
The grass is tall, it covers me.
Astral stealth shouldn't be really much different than normal stealth. All the same things apply. "But your signature extends blah centimeters from your body," you say. Yeah? So, what. Dunno 'bout you, but when I play hide and seek, I don't rely on the aura of a handy rock to extend six inches (what's that in metric, 0283028 kilometers, right?) out and obfusciate your vision.
"But, y'know, you're hiding with a gun, and watching, or something, maaaaan," Yeah. OK, fine. So my head is peaking out from the side of my rock, and you can see that glowing, but unless you're a total rules junky, the beauty of abstract games is that it just doesn't matter that much. Cause, y'know, the astral.. alive with pleasure, like a Newport, or whatever.
"Fine, but I'm gonna specialize in Stealth (5) Astral (7), explain that!" Sure. You understand the nuances of astral perception, and how to maximize that. Big deal.
"Fine, but if you're like.. stealthing from like, y'know.. a door to the car.. Or something, right? Then whatchoo hiding behind, glowboy?" Got me there! But, y'know, that abstract thing is about to bite, again. Coz, yano, stealth..more than just visibility. Being quiet, knowing how to move without presenting a target, etc. Lots of stuff in there, beyond the glowing aura bit.
There's no reason that astral perception should be the end-all in anti-stealth abilities. Its just one of many, and while you may glow like a virgin on prom night on the astral, there's no reason that you can't use all the other glowing stuff out there to your advantage either.
But that's just one man's opinion.
Except its mine. So its right.
