Shadowsmith:
I have a magus with Short Range Magic and Minor Magical Focus (Self-Transformation).
If he enchants an item to shapechange the user, does his focus apply?
That seems to entire lack "self."
Shadowsmith:
If he enchants an item with the ability to change its own shape, does his focus apply?
I wouldn't think so, but I see what you're thinking. You're letting the item transform itself. In my mind, the magus has the mMF, so it's the magus's self here. It's also one of the most powerful mMF available, only a little under the animal mMF, so I wouldn't think it needs any boost.
Shadowsmith:
After he bonds a familiar, will his focus apply to an enchantment that changes his shape to match the familiar's?
I would think so. It's still his own shape that is being changed.
Shadowsmith:
If he enchants his talisman with the ability to transform into a giant bear, can it continue to function as his talisman while a bear? If the bear is killed, what happens to his talisman?
Ugh. Well, killed is probably easier than hurt. I would look at the rules for damage to items in C&G. From there I would try to relate the wounds taken to the damaged/broken scale. I would think killed = broken.
Shadowsmith:
If he enchants his talisman with the ability to transform from its natural shield form into a bear skin cloak, can he still use the Shape and Material bonuses that no longer apply but are attuned? Can he now attune it as a Cloak as well as a Shield?
People go different directions on this. Basically, it boils down to essential nature v. current form determining bonuses. I really dislike current form myself, as it opens up so many problems that I feel you have to start making lots of arbitrary rulings to contain it. I far prefer the essential nature route myself, which would mean the bonuses are always based on it being a shield.
