Thanks a lot for your input.
Well, the book does mention it for for redirecting spells (YS260). And I think it’s implied for rotes. Part of my confusion stems from this.
I don't have my books on me so I can't look up that page number. For rotes, if you cast an attack spell, you don't have to control it but you still have to roll 'to hit'.
For a Rote maneuver or Rote Block there's no need to roll anything. The opponent rolls to defend against the Power of the Rote Maneuver which is automatically controlled.
Also, 2b doesn’t really makes sense without a targeting roll. If you only compare shifts of power vs. defending skill, why would the actual skill value be important?
The Power IS the targeting roll. Just like blocks, you don't have to target with discipline. The Block = Power invested and the opponent has to overcome that block if he does an action that the block effects. You don't dodge blocks.
You dodge maneuvers, but you dodge the Power of the maneuver.
I'm not sure why skill value is important other than the fact that it requires more 'minimum' power to affect a more powerful target. (before taking into account random chance).
Like the example I used with 'well lit'.
Using a fire evocation to light some candles on a scene might be a Power 3 spell that creates 'well lit'
Creating a massive hole in the ceiling that will allow sunlight to stream in and create 'well lit' might be Power 6 or higher because destroying a ceiling is harder than lighting a candle - and harder to negate with a counter-maneuver.
The former allows people to see and avoid compels revolving around darkness, the latter allows you to hurt vampires.
but maybe comparing shifts AND having a minimum shift requirement is redundant. Maybe you'd just do one or the other...but I like giving a person a chance to roll and resist.
