The magus is the one with concentration. The item is something other than the magus. The item maintains it for the magus. This is not the same as the magus maintaining it themself. It is Hermetic magic maintaining it for the magus. But, as I said, you stepped away from that contradiction and started looking for an alternative.
I can find it later. Basically, MuVi cannot work at all with normal targeting rules. He said we have to blur the lines for MuVi to work at all.
That would be this statement:
You cannot touch the spell itself.
Pretty explicit, no? That statement is attached to the paragraph on both your own spells and others' spells. You can't touch your spell, but you count as touching it. There is also nothing that restricts this to MuVi.
Not at all. You're making a huge leap to mistakingly state what my reasoning is. A person's mind is a part of the person. Repeatedly the rules show that you can touch an object to affect part of it. But a spell on a person is not part of that person. Its effect may change a part or the whole of a person, which is a different thing than the spell itself.
It's explicit that they cannot be touched. But for your own spell, Touch is considered sufficient for MuVi.
I meant by "stepped back" that you were no longer insisting on this, recognizing you were making an assumption that might not be true. You seem to agree with me since you just stated this yourself explicitly.
Here is the key to coming up with a consistent framework for it. These must be valid:
- You cannot touch a spell - explicit core statement. (This may be broken if you give a spell substance through Animae Magic, but Animae Magic is already a special exception.)
- Touching someone who counts as touching a spell is insufficient for Touch - otherwise more Range than Touch isn't necessary for someone else's spell.
- Maintaining the Demanding Spell works at Touch - It's R: Touch in core.
Additionally we know:
- For at least MuVi you are considered to be touching your own spell. This may or may not apply to other TeFo combos. (Edit: Technically it does, but we're not sure for how long a spell is considered your own vs having departed from you in some sense.) I state it here as a reminder that using it to solve the problem could be one of the most consistent ways to make things work (Edit: especially with some other "your own" or similar language).
If a framework doesn't work for those requirements, it's invalid. Mine holds so far.
Then you want to examine this next, which must also be true:
- Suppressing the Wizard's Handiwork works at Touch - It's R: Touch in core.
If a framework doesn't work for this as well, it's invalid. Mine still works here since the spell at least works for Concentration spells. But mine is a little ugly here, as I think this is probably supposed to work on non-Concentration spells and I haven't generalized my framework that far yet.
