Ugh, another session where I'm stuck helping with DM stuff. Look, I know the books better than most people, so I guess this makes sense. But I'm telling you right now—I'm not hiding behind any screen. There's already one too many of me out there as it is.
Anyway, what do you need? Rules lookup? Encounter balance? Trying to figure out if that spell actually works the way your player thinks it does? I've got the books right here.
