I ran it in stella and it was fine, but I could easily have played without it. My experience is that its pretty rare that you enter a location with an unengaged enemy and you don't want to damage it this turn.

If an enemy spawns at another location either it spawns on another player in which case it won't engage you, or its the kind of enemy that spawns elsewhere to force you to chase it down and kill it, like a cultist. Stella in forgotten age seemed like an ideal case for this card, and it was fine. It allowed me to walk through snakes trivially and things like that, but I cant imagine it being a huge standout in any deck.

I haven't played it yet, so I don't have a good read on how well it works.

Here's the list of investigators through Drowned City that can take it: Amina Zidane Diana Stanley Father Mateo Lily Chen Sister Mary Stella Clark Zoey Samaras
