How to Get Trap Spotter Talent

[OutsiderSubtype]

I am looking for ways to get the Trap Spotter rogue talent or an equivalent ability.

Here is what I know of so far:

1. Be a Rogue
2. Be a Ninja
3. Be an Archaeologist Bard

Are there any others?

Please note that I said Trap Spotter (which lets you automatically roll Perception to detect traps). Trap Spotter is not the same thing as Trapfinding (which adds bonuses to your rolls to detect and disable traps) and is also different from Trap Sense (which benefits your saves and AC against traps). I know that there are lots of other ways to get Trapfinding but I am asking about Trap Spotter specifically.

Thank you for your help.

You can take levels in Crypt Breaker alchemist; they can pick that as a discovery.

Thanks. Looks like there might also be some Prestige Classes that grant it (Halfling Opportunist and Sleepless Detective) and some third-party classes that grant it.

Anyone know of anything else, especially anything that mimics the autospot ability?

Who has so many problems with Traps?

I know traps aren't a big deal in most campaigns, but I'd like to see if there's a way to get the convenience/time savings of the Trap Spotter talent with less investment than 2 levels in Rogue.

Shadowdancer PrC.

White Haired Witch archetype.

Neither is very good, and would involve a wait to get it, but they're options...

Stonecunning is sorta similar, dwarves get it for free.

Deep Earth Bloodline.

For anyone else reading this, I've found that the Feral Child druid archetype is another way, although it only works in favored terrain.
