I’ll add: The text never specifies how to handle an incantation like Sleep if taken as a Rote, even though it’s effect is specifically based on rolling. This still bugs me, so I may add some text to clarify later! But for now, my intent was that you could make a judgment call in context, such as to say it still poses a risk (as described above with Bolt), and so you still roll, or it affects only one target.
