Well, you guys do seem to prefer that the noobs with little idea how the rules work keep their questions and ideas contained in single threads, so... I guess I'll save you the pain of having to get annoyed and then stick me in a solitary thread, and just seal myself in one.
Anyway, let's begin!
Obviously, "artificial intelligence" in the sense of creating a computer capable of intelligent thought and feelings is a recent fad on the scale of human history. But would the ability to create intelligent life be considered a big deal in Ars Magica? (Note that "intelligent" does not seem to require "with a soul" in Ars Magica, given that Magic creatures can be intelligent.)
Related to my parenthetical above, it seems there are a few ways for a magus to become a creature of Magic or Faerie. (There may be ways to join the other two Realms? I am unsure.) Would a character who took one of these paths keep their soul, despite Magic and Faerie creatures not normally having souls?
I had an idea for a Wreath of Flames spell. I was thinking you'd do this with the level 20 Creo Ignem guideline for creating damage +20 flames in an unnatural shape (in this case, like a cloak around yourself), making it with a Rego requisite to avoid burning yourself or your stuff... It'd be Touch range and, I dunno, either Concentration duration or Diameter, depending on if you wanted to be able to fight with it active. So the total level should be 30... If a large campfire's flame would be enough to do that. That's a really vague size. Problem, though... Maybe I'm thinking with my modern brain too much, but would the caster blind themselves with the smoke and flame so close to their face, even if it wasn't burning them, or could that be covered as part of the Rego requisite?
Can items with Personal effects be used to affect their wielders indirectly? Like, obviously, a ring with Personal range invisibility effect can only turn itself invisible, not its wearer, but if you had a cloak with a Personal-range effect to protect against fire and heat, and you shielded yourself from a dragon's flame with the cloak, would it protect you?
I can't find any guidelines for making armor stronger... I figure it'd be Muto Terram, but I'm not sure what level it would be or how much stronger you could make it. Similarly, what rate of magnitude-to-Damage would you need if you wanted to make a more potent "Edge of the Razor"? Or is that even possible?
A good number of folk tales have such things as "swords that can only be wielded by the rightful heir to the throne" or good jazz like that. So would the mythic paradigm suggest that a bloodline can be traced through something other than a given person's knowledge of the bloodline? If so, would you use InCo for that, or maybe even InVi if it's a supernatural property of the blood? Like, Excalibur got pulled by Arthur, and he didn't know he was an heir until he did so, so in Ars Magica terms, the item would've had a Linked Trigger based on an In(something) sensing the proper blood from the person trying to pull it. I want to know what Form that (something) would be.
That's all I've got so far. Thanks a bunch for helping me figure this game out, guys!
