BTW, according to the book, they start 120 feet away. So they are effectively blind to the party's approach (per the rules).Twig blights have Blindsight 60' radius.
Looks like 15 - 20 ft. Which is enough to kill a 4 hp twig blight.How high do you think the ceilings are?
No windows on ground level. Would have to scale to the balcony, break a window, etc. That would take a couple of rounds, if they could even do it. They have a 50/50 chance of hitting the window and can barely break it with their damage.It's a pseudo-medieval winery - you think it would have glass in the windows?! Even if it does, a glass has window has AC 13 and 3 hp.
