Hiding presence

[jason hammonds]

Is there a feat, spell or talent that will allow someone to completely hide their presence? I mean from blind sense and things like ki awareness (jade oath). I have a player who has a high perception and locating abilities, so it makes it near impossible to catch them unaware.

Well there is Dampen Presence.
That should help with blind sense, but I'm unsure about ki awareness (I failed my interweb-search skillcheck).

You could also try to hide in plain sight.
This can be done at least two ways, such as hiding in a crowd (PC sees/senses presence of lots of people), or a betrayal (PC knows they are there but doesn't expect a fight).
Notes: A crowd could be a crowd of people in a street/shop/city or creatures in a jungle (there's lifeforms all around). The betrayal could be an actual betrayal (their friend isn't their friend), or just a disguise.

Without knowing more details it is a little harder to think of ways around this party's defenses.
Could always try to catch them when they are asleep.

Although in saying this, you should still reward them for getting the ability to not be so easily caught off guard.
