My DM says that there is only one specialization for either Control or Complexity for conjuration or wards etc, OR Strength or Frequency for enchanted items, but I say these are two separate things.
They are separate things, i.e. let us say you have Thaumaturgy. On your Thaumaturgy specialization, you go with a +1 Crafting Strength.
You then get a Refinement and you go for two more specializations, so you grab another +1 Crafting Strength and a +1 Divination Complexity.
Your specialization list looks like this:
- Crafting +2 Strength
- Divination +1 Complexity
Note the pyramid - you cannot have a +2 without a +1 somewhere else.
You get a second Refinement, and again you get two more specializations. You want to get a +2 Frequency to Crafting, so you would look like this:
- Crafting +2 Strength
- Crafting +2 Frequency
- Divination +1 Complexity
... but again there's the accursed pyramid. So you ditch +1 in Crafting Frequency and put it into Divination Control instead. Your specializations now look like this:
- Crafting +2 Strength
- Crafting +1 Frequency
- Divination +1 Complexity
- Divination +1 Control
You'll have to wait for another Refinement to bring that Crafting Frequency up another +.
The discussion also involves the debate whether enchanted items belong exclusively to Thaumaturgy; or if you only have Evocation, could you make a ring of force like Dresden has? If you could, then the Crating Specialization is in effect, when you don't have Thaumaturgy, which makes Crafting Specialization and Thaumaturgy Specialization two separate things.
We await your input, thanks.
If you only have Evocation, you can still craft focus items. However, no enchanted items or potions for you.
