Re: In the Ninjas' Lair
"There is a spell I know of that might be helpful here. It creates smoke, but without fire. The smoke irritates, and blocks vision, because it is real, dense smoke, but it is no more toxic than smoke from a wood fire, so would do little if any harm to innocents, and it dissipates in a few minutes.
"If there is a back way into the kitchens, filling the kitchens with dense smoke that spills into the stairwell and then out into the dining room would result in, at least, a distraction. It might cause guests and even staff to evacuate the house. Otherwise, doing the same in the dining room would surely cause diners to leave, though that would be more likely to cause injuries.
"I do not yet know this spell, but I know what I need to learn it, and could do so in little more time than it takes me to walk to the Guild and return."
