So if I have this right, when one of my characters is using a thaumaturgical ritual, lets say creating wards, then the ward strength and length are determined by how many shifts of power, in total, the character can summon. These shifts get split between desired effect strength and how long the effect will last, right?
Also can the player spend multiple turns, gathering a small amount of power and controlling it every turn, to get a whopping number? For instance, Dan gathers 3 power per turn for 10 turns. He now has a total of 30 power? That seems outrageous to me. He invoked no aspects, just spent time on gathering and controlling.
Thaumaturgical rituals are split between strength and duration like evocations, right or wrong?
Can a character use multiple turns to gather energy for thaumaturgy?
