Probably still a strong difference between Intuitive Magic and Threadmagic...or not. I don't know. Everyone can get at least Blast I, Chi I, and Healing I. Nethermancy adds Summoning (3), Chi (+2), Influence (2), Life (3, mostly unlife), and some Divination (1) and Healing (+1), for a total of 12 more spheres. Illusion adds Blast (+2), Illusion (3), Influence (2), Light, Sound, and some Summoning (1) and Movement (1), for a total of 11 more spheres...hmm. Have them not be able to do healing, but allow, say, Movement II, Chi II, and Life I--sound is not quite a bum sphere when you have Illusion. Elementalism adds each of the Elemental Spheres (4), Chi (+1) Life (2), Movement (3), Weather (1), and some Summoning (1), for a total of 12 more spheres. Wizardry adds Blast (+1), Healing (+1), Chi (+2), Divination (3), Movement (2), Influence (1), Sound, and Light, for a total of 12 more spheres. Shamanism adds Healing (+2), Blessing, Divination (1), Influence (2), Life (3), Weather (1), and Summoning (2) for an additional 12 spheres. They might be able to trade some in for elemental spheres instead. This means every Adept spellcaster eventually gets 15 spheres. If the gain is one per Circle Advancement, you'd have to start at 1 to hit the right level at 15th circle. It's much nices to assume that Adepts start developing additional abilities after, say, circle 12. A standard starting Nethermancer has (Healing?) Summoning, Life, Blast, and Divination. A starting Illusionist would typically have (light?) Illusion, Influence, Blast, Movement. *Jenna would now have Light, Illusion, Illusion II, Influence, Summoning, Chi, and Blast. We've seen her cast the Light spell, she's definitely using Illusion and Illusion II, the Influence spells like Madness, Summoning a purple elephant, Chi to be able to create magic items, and the wiggly green worms are definitely a Blast effect.* Elementalists would start with (Blast?) Healing and three of (Earth, Fire, Water, Air, Life) Wizards would begin with Blast, Divination, Movement, Chi (only ones to start with it), (and Influence?) Everyone gets Chi for circle II (you can now make magical items), except for wizards, who pick up Movement or Influence or something. It's possible that there are just three other schticks that are important to mages that show up just as part of "And now you're another circle bigger" and not specially purchased advantages.
Skew, and matrix sizes...I'm guessing that a Spell Matrix can hold any effect from a sphere that doesn't have a numeral after it, and that a Spell Matrix II and a Spell Matrix III can be learned (this might replace, or add too, armor matricies and such). As most spells seem not to have anything resembling a cost, what to do about Skew? Is it still around? Is it the same for every *Sphere* II effect, given uniform ambient astral space?
I disagree that the wiggly green worms are Blast; I think it's more likely that they're Illusion II. I'm hoping to keep high-level Illusion for Illusionists (duh), Chi for Wizards, Summoning for Nethermancers, and presumably the full Elemental set for Elementalists. My original intent was that a Spell Matrix can hold any effect, and once you know the Sphere II or Sphere III, you can cast those effects and your matrices cope. Skew will likely leave, though note many Sphere effects cost magic points (which regen per session). My intent for Raw Magic is to mimic the Arcanowave Mutations / Warping effect: keep a running total over each session, roll vs. it at the end to see if it has any bad effects or dissipates harmlessly. Each 5 points of such temporary Taint becomes a point of permenant Taint. You get a point every time you cast raw, +1 for every magic point involved, +1 or +2 if you're hurrying, plus the amount by which you failed if you botch. Thus, critfailing a major ritual which you were rushing through is a great way to become a Lich. I agree with most of what you've got above, though I'm not *totally* convinced that the Blast schtick is necessary, only the Blast effect (which is in Illusion 2, Fire 1, and a few other places). --bts
