Sense the Unseen
FEAT 14 reaction
You fail a check to Seek.
When you look for foes, you can catch even the slightest cues, such as their minute movements or the shifting of air currents on your skin. Even though you failed at the triggering check, you automatically sense any Undetected creatures in the area where you're Seeking, making them merely Hidden to you.
