Trap Finder Feat 4*Investigator Rogue Source Player Core pg. 169 2.0,
Player Core 2 pg. 107Archetype 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.
Archetype Use
This feat can be used for one or more Archetypes in addition to the listed Classes. When selected this way, the feat is not considered to have its class traits.
