+2 to Disguise and Bluff... what's the feat?

[Dr Midnight]

Edit: never mind, forgot about the synergy...

There is the synergy bonus, but there is also a feat called deceitful that does in fact give you a +2 to bluff and disguise. I do have to say that the "+2 to two skills feats" generally aren't worth it, unless you really, really need to bump up your skill checks.

Or, the feat itself is need for a PrC. Can't think of one, off-hand, though.
