Intellectus Of War [-3]
Musts: High Aspect that Corresponds to this (Scion of a War God, Empowered by a War Spirit)
Key Skill: Fists, Weapons, Gun, Drive
You are a living embodiment of combat. Anything is a weapon in your hands. You could man a tank even if the last time you were on Earth was when gunpowder was considered an innovation.

You may substitute your Fists and Guns skill with Weapons. Furthermore, you can substitute Weapons for any skill roll as long as it could be considered an attack or the vehicle could be considered a weapon (so your Weapons skill could not substitute your Drive skill, unless the vehicle was a tank, a fighter jet, or you were actively trying to run someone over with it). You are considered proficient in any weapon or weaponized vehicle, and you could substitute for other crew, within reason (so you could operate a two-man fighter by yourself, but a battleship is right out). You instinctively know how to maintain weapons and weaponized vehicles, though you cannot teach anyone else how to (so if the item is beyond the capacity for one person to maintain and you're alone or with unqualified people, you're SOL).

You may not gain these bonuses in terms of spellcraft, except for the purposes of aiming an Enchanted Item.

Don't care, on that one. Just don't.

Sorry if I'm being mean.

Power bonuses always add to the conviction score of the character. Control bonuses add to the discipline of the character. I suppose that's the way it is for both evocation and thaumaturgy.

There's no such thing as a Power bonus for Thaumaturgy. It mentions on 181 the rolls, so I guess, there is no way to increase your Conviction WRT Thaumaturgy.

I think the easiest way to cover this would be to explain the process and each skill's part in it.

First you figure out the complexity of the spell and then try to match that with lore + other bonuses (I'm glossing over that bit, it's a bit more complex). Once that's done you (eventually) have to summon enough shifts of power to match the complexity. This is done as a series of simple actions similar to individual evocations where the caster draws as much power as he likes (any amount between 1 and his conviction plus any power bonuses for no stress, each one after that costing one additional stress) and then attempts to channel that into the spell rolling his discipline plus any control bonuses and attempting to get over the amount of power drawn. The drawing and controlling of power is done repeatedly till the complexity is matched and the spell works, or until the caster mucks it up (which is usually pretty bad, but depends on how high the complexity is and how far into the spell you are).

Does this answer your question?

So, what you are saying is that it does not add to the Conviction score of the character for the purposes of spellcasting, unlike with Evocation.

I fail to understand your point. We're not talking about using theory in game. We're talking about legitimately hexing the ever-loving hell out of things in game. Which I do suppose is a fair bit odd; hypotheticals within hypotheticals vs supposed reality within hyoptheticals.

From what I got from tutori's posts, he seemed to be insisting that Luccio could use a computer, given computers are her hobby, she has a lot of control, and that a purely theoretical interest wouldn't make any sense. I was countering his argument by arguing that Luccio never stated she ever used one, countered an inquiry into her hobby with an explanation that would not run contrary to a wizard's paradigm of screwing up technology, and cited an example of someone having a purely theoretical interest in something.

That sounds... awesome. 

All my games have mostly died before I got around to our badass moments. 

It was even better as the NPCs were doing it too.
