You know, I wasn't expecting this kind of PvP here :p
But since we're doing this, no holds barred, eh?!
j/k

Anyhow, I was thinking, I was unaware of the whole spotting-she's-elven thing.
If Silk was aware of this, and is passing through life as a human though, it kinda makes sense for her to be trying to hide/disguise her elven features in daily life, no? At least when she's carrying a human SIN...
So here goes:
Disguise (5d6.hits(5)=3)Which would mean John/Snakebite doesn't spot a thing.
*shrug* Up to Sent to allow it or no...
Not -really- a problem for me, though I'd welcome it.
This new way of ruling Human Looking can actually play out pretty good. Sure, she can be detected. But that means that when she's actively trying to pass for an elf, it'd be easier on her too, right?
Word of advice, though, IF your character spots her true nature and isn't completely socially inept, he'd probably know: She's obviously trying to hide it, she may not appreciate you mentioning it.
