This one looks a little harder to me. You lose one maximum sanity each turn you end the mythos phase in the street! This seems like it will make killing monsters a lot harder... though there does seem to be an item that might help a lot (that I thought would never be that useful...).
Is there any way to ever regain maximum stamina?
Does -1 stamina loss help at all? Do the items that prevent stamina loss from one source help at all (can Flesh Ward protect you in the streets?)
Questions about the clues in the woods: does taking them allow you to avoid having an encounter in the woods? If a gate appears in the woods before you get the clues, do they go away?
