Instincts and Checks

Quick question:

If you have an instinct related to camp (I search for water whenever we make camp) do you need to spend a check to use it? I know that instincts are free rolls in the adventure phase, but it’s pretty ambiguous in camp.

Also, would you be able to use an instinct (I always search for traps whenever we enter somewhere new) every time you entered a new room in a dungeon?

I don’t have a page reference for you, but instincts don’t cost checks in camp.

And yes to the second, but note that if there’s not actually any trap then no roll is necessary. And the GM should still ask how they’re searching for traps when they enter the room. “I search the room for traps” doesn’t fit with the Describe To Live rule.
