So my friends started a pathfinder campaign while I was out of town, but since I'm going home soon, they invited me to join in. The catch is that the rogue left the game recently, and so they need someone to fill in the role of trapfinder. Sounds fine right? Well... The classes with Trapfinding (aside from Factotum, we'll get to that) all seem really boring to me, and I don't want to play any of them. To make up for this, I've been looking for ways to finagle my way into being a capable trapfinder while also making a fun character.
My current thought up ways include a level 1 factotum dip for all the class skills ever, which would allow me to be an amazing trapfinder and also have fun with Iaijitsu Focus (although I would need to find a way to force flat footed easily), heck I'm even considering straight Factotum for Cunning Surge, although I feel like I become a 1 trick Pony in combat by doing this. The other option I'm considering is using the Oracle with the Wrecked curse, which allows me to disable device, and then just use detect magic into an at will item of dispel magic I read about somewhere to deal with non-magical traps. Of course, that becomes something of an issue if I try to Gish (which I kind of want to try) since everything I touch is considered broken.
The campaign starting (or joining, rather) level is 4. The party consists of a Monk, Wilder/Dread, Gunslinger, Vitalist, Sorcerer (blasting, but encouraged to take spells like Enlarge Person and colour Spray) Ranger (bow until they get close, then charge with Greatsword) So I feel its safe to say I don't want to get too stupid with my power level, my only real baseline of power is that the monk is proud of dealing 2d6+15 per hit when power attacking and enlarged. The egotistical part of me has taken that as a challenge, and the rational part of me doesn't want to go too far with that because I want to keep things fun for everyone. We are allowed anything form Pathfinder and 3.5 as long as it is not Homebrew. Any advice?
TL;DR: I need a way to tack on good trapfinding capabilities to a level 4 without taking too much investment so can make a fun build.
