Sneaking
Dice Pool: [Dexterity + Stealth]
Discussion: A sneaking character uses Dexterity + Stealth as a resisted action against Perception + Alertness rolls from anyone able to detect her passing. The difficulty of both rolls is typically 6. Unless observers score more successes than the sneaking character does, she passes undetected. Noise, unsecured gear, lack of cover, or large groups of observers can increase Stealth difficulty. Security devices, scanners, or superior vantage points may add dice to Perception + Alertness rolls. On a botch, the character stumbles into one of the people she’s avoiding, accidentally walks into the open, or performs some other act that compromises her.
Note that vampires using the Obfuscate Discipline may not have to make rolls at all.
