You can't say that any "hostility" is on the part of the listener. It goes both ways, I can't interpret hostility out of wholecloth. Well, I could, but I'm not.
Instead of the longer thing I came up with on the drive to work, I'll just say this: Yes, I know how Thaumaturgy works. And I know how Evocation works. And it annoys me when someone feels they have to lecture me on things I already know, when I thought I had made it clear that I already knew.
In the interest of getting this back on topic, I'll rephrase the question so that things are clear.
With Evothaum, you get the effect of a Thaumaturgy spell (normally the complexity), with the methods of Evocation (power). Ergo, with an evothaum spell, the thaumaturgic complexity is interchangeable with the evocation power--they're both the end result, total effect of the spell defined by the number of shifts of power you can put into it. An Evothaum spell cast with a power of 8 has an effect equal to a thaumaturgic spell cast with a complexity of 8.
So, my question is, do the focus items (or specializations) for Thaumaturgy that add bonuses to the total shift effect of a spell and the control rolls for a spell keep their bonuses when spells of that type are cast with evocation's methods and speed?
Say you have a necromancer with a focus item to add +2 to his Great Lore for zombie-raising rituals (meaning he can at a moment's notice set up a 6-shift complexity ritual) and another item to boost his control rolls by +1 for casting the spell.
If he then picks up Kemmlerian Necromancy, can he use the bonus from those focus items with his Good Conviction and Great Discipline to help him cast a 5-shift insta-zombie spell? Or would you need separate focus items tied specifically to the Evothaum versions of the spell?
