Does Pathfinder have an Unseen Seer equivalent?

[tadkins]

Just wondering. If I wanted to port over the classic Whisper Gnome Rogue/Wizard/Unseen Seer build from 3.5 to Pathfinder (assuming my DM wouldn't just allow me to "translate" the class), is there a way to do it with purely Pathfinder material from the PF SRD?

I think there's just Arcane Trickster, which is easier to qualify for in PF at least. There is even a feat to give you +1d6 sneak attack now so you can get in with a quick dip or VMC.

Beyond that, if you want the unique benefits that Unseen Seer provides, your GM shouldn't have a problem letting you port it in.
