Description: Your senses are so attuned that you can detect mechanical traps that are close by.

Prerequisites: Trap Sense +2, Elf or Trapfinding feature

When you pass within 5 feet of a mechanical trap, you are entitled to make a Search check to notice the trap as if you were looking for it. You cannot sense magic traps or spell traps with this feat.
