Trap Finder Feat 4*Investigator Rogue Source Player Core pg. 169 2.0Archetype Archaeologist* This version of the Trap Finder feat is intended for use with an Archetype and has a different level for access than the
original feat.
You have an intuitive sense that alerts you to the presence of traps. You gain a +1 circumstance bonus to Perception checks to find traps, to AC against attacks made by traps, and to saves against traps. Even if you aren’t Searching, you get a check to find traps that normally require you to be Searching. You still need to meet any other requirements to find the trap.
You can disable traps that require a proficiency rank of master in Thievery. If you have master proficiency in Thievery, you can disable traps that require a proficiency rank of legendary instead, and your circumstance bonuses against traps increase to +2.
