Ars Magica Magic resistance and spell cancellation

Posted on the GO board, but I'm looking for opinions on this for the weekend, so I thought I'd try a broader audience...

On the face of it I am quite confident about applying magic resistance rules, even the crunchy rego-ed hurtling objects bits.

Last night the troupe were planning their attack on a faerie lord (fairly justified if you allow for the pre-emptive option) using the knowledge that while it was not harmed by cold iron it can easily be bound by the stuff.

One of the ideas was some device - cloak, robe, other wearable gift threaded with iron - or simple iron bar which would be muto-ed into a harmless metal. The idea is that when the item hits the faerie's magical resistance, the spell is cancelled and the item returns to its natural (and therefor harmful) state, binding the faerie where he stands.

But is this within the flavour of the rules?

I am torn as it is another great idea from Dave which sounds plausible but I am not sure that a muto spell acting on another object would be challenged by the magic resistance of something in its way.

The classic example for rego (the magically thrown rock) I understand. Without using finesse to do something fancy with the rego-ed rock (lobbing it rather than guiding it to its target), magic resistance comes into play as the magic is trying to force the object to the target.

But in this case, the magic has nothing to do with the target and is confined to the object itself.

I think we are looking at the alternative of a simple concentration level spont to have much the same effect as there is a little doubt as to how reliable the MR approach will be.

Anyone else come up against this kind of situation? How did/do you guys handle this one?

MR doesn't cancel spells. It's a ReVi effect not a PeVi.

The magically altered object bounces of the target and the spell continues for its entire duration. The target can pick up the object, still the spell continues.

It could eat the object and would suffer the material's true effect when the spell expired.

The simple answer to that question is that the Muto spell only affects the iron. Therefore, all of the magic is bound within the item, and thus, the Magic Restistance of the Faerie will not repell the spell.

The spell would need to target the Faerie specifically, either directly or indirectly. Just as a shapeshifted human doesn't change back if they hit a mage's Parma or the MR of a giant.

Yeah, thanks guys. That fits with my conclusions. I think the magi will have to go to plan "b" - the sponty-conc approach so they can change the item back at will (or when the concentration fails...).
