Little confused about exactly what has to be locked down when creating a rote. Some of the defensive rotes described let you chose between block and armor, or chose how many shifts to devote to duration, but are still considered rotes.
Is the same flexibility available to an offensive rote? If you have a fire attack rote, do you have to specify that it always attacks one target, or can you decide when casting the rote to devote two shifts to attack a zone, or split the attack up among many targets?
