Observant (Fallout Supplement)
From D&D Wiki
Call it a sixth sense, paranoia, or just an overly cautious nature, but you tend to notice when things are out of place. You are always subconsciously checking for traps in the vicinity.
Prerequisite: Level 2, 4 Ranks Spot
Benefit: Whenever a character with this talent comes within 10 feet of a trap or hidden door, she receives an immediate Spot skill check to notice the trap. This check should be made in secret by the GM. You also gain a +1 bonus to your Spot skill checks.
