Agreed. It's still useful and still worth the work of codifying, IMO -- "enable a cavalry charge over shitty ground" seems like the ideal use case for wizards who aren't sufficiently Misterious to cast it for strategic-level movement. But I don't think it's a high priority, it's just something we can do on future turns to pump up Mathilde's LM cred.
Sure, but that wasn't a case of looking at a divine artifact; we were explicitly doing something actively hostile to Stromfels, trying to destroy his shrine and cast out his divine influence. Let's say Mannslieb is secretly Manaan; is it overly dangerous to just investigate an artifact that might or might not be Manaan's in order to figure out who's home?
...actually, now that I think about it, yeah, kinda. You've convinced me, this is definitely a "moderate" failure sensitivity. Good talk.
