I have a character that is styled after Sherlock Holmes (from the books), with a touch of Batman and the Punisher rolled in (basically, he's an investigative vigilante who has no qualms about executing those he judges as guilty). Right now it is a Spellthief 1/Wizard (Diviner) 5/Incantatrix 1. I plan to go into Unseen Seer after Incantatrix 3 (or 4).
There are a million feats that I want for this guy, but of course I can't fit them all in. I did pick up the
Investigate feat which is excellent for this kind of character (and probably useless for most others), and of course Uncanny Forethought because it is the best wizard feat and fits this kind of super-genius tactician to the T.
I've been considering swapping out the Spelltheif level for Urban Ranger for the Urban Tracking feat, but I'm not really sure it is worth what I'd lose. It seems like to me that the "normal" usage of Gather Info should get you enough information to find out where people you're looking for might be, and then you could use other methods (stakeout, infiltration, scrying, etc) to determine which one they are actually in. So this feat really isn't doing much that you couldn't do without it.
I'd be giving up some Sneak Attack, Trapfinding, and the future capacity to steal/borrow higher level spells (and Persist them) via the Master Spellthief/Incantatrix combo. So... I think I've basically answered my own question here... Just wondering what others opinions are on Urban Tracking, really.
Edit: I guess it
explicitly lets you track down people using Gather Info, and it shortens the time required to 1 hour (instead of 1d4+1) per check. Is that worth a feat (or trading out class levels)? Probably not.
