People have screamed bloody murder about Outlanders using facilities within cities, and yet I've had Outlander leaders who would commonly barter for goods and services while within town. Whether your characters can do that will depend on your role and the zeitgeist.

Assuming the spirit of the time doesn't dictate your roleplay, your character could potentially use the instruments of civilization to help civilization self-destruct. Just as a villager might chase a mage through a magical portal, your character might barter with the city healer so he can resume his raid or retrieval with the despicable forces of the Spire. As Patton said, "Wars are not won by dying for your cause, but by making those other bastards die for their cause." Owlbear feathers for the win.

But I will be candid: there is a reason why there are no healers at your recall points. You, as an outlander, in the name of self-sufficiency, are supposed to die when you fight your nemeses, the antipaladins and necromancers that populate your cabal enemies. You are not intended to recall and spam heal to avoid death from fighting a dagger specialist nor heal a scourge or cure blindness. You are an enemy of civilization, a criminal who is supposed to struggle immensely when retrieving against two of your three enemies. The Empire and Scion cabals have powers that by their very nature greatly hamper the powers granted to Outlanders.

As a new player, expect to suffer. Understand that many veterans looking to powergame will play other cabals. Play Outlander for the roleplay and for the vaunted freedom the cabal offers.

Statues are erected in civilization for those who dominate their foes, but stories are sung by those who struggle to overcome their handicaps. Therefore, when you play an Outlander, befriend a bard.
