The follow is the system we are using to determine how easy a PC or NPC is to find and how good they are at finding others.
The difficulty to find someone normally = Haven + Resources + Stealth + Obfuscate, if they are using Earth Meld, substitute it for Haven.
The difficulty to notice someone when they are actively looking for someone else = Stealth + Obfuscate, where a group uses the lowest total unless they are under Cloak the Gathering in which case 5 Obfuscate + lowest Stealth
The ability of a PC or NPC to find someone else = Auspex + Investigation + Hunting + Time where time is the number of months you have spent looking.
The ability of a PC or NPC to notice someone looking for them = Auspex + Investigation
Note: There are occasionally other modifiers for specific powers, but they are on a case by case basis.
