Someone at the FFG Forums posted the information:
When hero in your los starts turn, he may recover 1 hp and get 1 mpvement.
Or any hero may discard condition for flipping search card.
Both cost you 1 fatigue
+2 to every attr during travel
Exhaust-you and each adjacent hero may move 1 space.
When a hero in los recovers hp, also recovers fatigue. Test will power after or exhaust.
Each other hero may use your search cards.
Also costs no fatigue
