EDIT: Of course, this also means that a spellcaster can do Weapon 1 attacks at their Conviction score-1 for accuracy for no mental stress so long as they can make the Control roll and their Lore (or Complexity) is at least equal to their Conviction...interesting.
Perhaps an answer is to require a Fate point any time a player wants to do a Thaum spell at combat-round speed? This would make it generally possible to do when you *need* to do it, but would make it too 'expensive' to do regularly...
This is a good notion, though I'd make sure to qualify it with "if the game table agrees it's dramatically appropriate".I think I'd probably consider almost all of the rules to have that caveat, but true enough. ;)
[edit]
The spoilered spell need not have been thaumaturgy. Harry could have just been taking a few exchanges to do maneuvers, which he then tagged to cast a much bigger than normal evocation spell instead.
I'm not sure why you would think that such power couldn't be drawn for Evocation. It could have easily been a Declaration or Assessment resulting in an Aspect that he then tagged for a bonus to casting.
evocation is too quick and dirty to use other power sources the way a thaumaturgical spell can (page 267).
That said, I just re-read the relevant section of the book, and it's hard to believe that a spell that powerful was an Evocation, especially given that it was in an element he was weak in. Then again, one could argue that "Earth Magic" implies Evocation, given that the divisions are different for Thaumaturgy.I think somewhere in the description in the novel, it mentioned that is took Harry about a minute to cast the spell, which again suggests that it wasn't an Evocation since those castings are immediate, with possibly some effort of will/shifts to provide duration once the spell has been cast. And I agree, that was big. Sort of makes me wonder what would happen if Harry did the same thing at the home of a certain dirty Internal Affairs cop...
Bottom line? Could be either. But it was big.
The issue with that is the book specifically mentioned he tapped into the leyline for additional power, per the RAW, Evocation power is determined by a caster's Conviction, plus appropriate specializations and foci for power, a character can't use Aspects to boost the power of their Evocation. Tapping into a leyline for power is either making use of Thaumaturgy or Sponsored Magic: Place magic.Check YS:250 item 4 under "How to do it". You can explicitly use aspects to add to your discipline roll when using Evocation.
By the way, I recall another instance that he did something like this. I think it was against a Frog Demon or some such, and he drew power from a storm to blast the demon. Storm Front seems likely to be the source for that one.
I'll have to go over the bits posted here about Aspect use for Evocation again. When I originally was running things and creating characters, it had made sense to me that Aspects could be used to give an extra 'bump' in power if/when needed for Evocation. As I said, something I came across which I can't remember where (of course...) then made me think it wasn't possible. Perfectly happy to use Aspects for extra power during an Evocation again. I did that during the playtest, much to the chagrin of a block of San Francisco in North Beach...Is there really a need to use Aspects to boost power for evocations? Consider that adding two to the power of an attack spell ultimately increases the stress inflicted by two. Increasing the control roll by two also ultimately bumps up stress by two. However, an increase on the power side makes it more likely to fail the control roll, while an increase on the control roll decreases the likelihood of a failed control roll, and also decreases the chance of getting dodged or blocked.

To quote King Lear, "question not the need!" :D
Considering mundanes can use Maneuvers to place Aspects to help with their Attacks, I see no reason to restrict Wizards from doing the same. Plus, we have a textual example of a spell benefiting from an Aspect: that Grasping Branches spell.
The real question is *when* it's appropriate:
I think it balances out. Boosting Power stands a higher risk of spell failure. Boosting Control is equivalent to anyone else tagging an Aspect for an Attack.

I missed that latter bit of timing. Yes, that make it sound very much like Thaumaturgy, though it still could have been an Evocation preceeded by a long string of maneuvers -- with accessing the Ley Line being the final maneuver.
Strong point considering the length of an exchange is so ambiguous. Did anything specific happen in the intervening six paras that would support there were exchanges going on? (Guess who hasn't read Changes)
