Oh!
How about having a return to city ability instead as an item? It’s so easy to forget. Maybe the city hands you one, if you don’t have one, on arrival? I do like the Slimes Request basically pays for it, early game. But it’s alot of clicks that makes the game more difficult.
The one thing that’s missing from Etrian Odyssey I’d like here is notations on the maps! You have such complex maps it’s easy to get lost.
