I've been thinking, and I reckon that the magic system could work like this (in practice)
- Select sphere to use (e.g. Life)
- Select target (e.g. Corpse)
- Select intonation (e.g. Angry)
And a likely result would be the ressurrection of the corpse, probably in an evil way (not conscious). Obviously that would take a particularly skilled wizard to pull off. Each stage would have limitations. Each sphere would have a skill level that you could improve. You may have to read magical books or go through certain experiences in order to access certain spheres (so you might have to fight a magma man before discovering the fire sphere). Initially you wouldn't even have the option of a target, you would just select the sphere and intonation and a fairly random effect would happen
somewhere nearby. Then you would gain the ability to select a circular area of effect and this area would gradually shrink until you could select the index finger of the kobold's left hand. Intonation could be a sort of experiment - certain spheres might be better with certain intonation, or might work differently. Anger would tend to lead towards less controlled, more aggressive magic, sadness would tend to be more calm, but still have a destructive tinge and happiness would cause things which make the user happy.
I think also the type of wizard could be important. It could be a little ambiguous, so that you think: "I'll summon a demon to destroy the town with an angry intonation" but because you are a wizard who delights in bloodshed, your anger creates a fluffy bunny demon that just goes around loving everyone. Or that could happen if you use a happy intonation, because you haven't been evil enough up until that point. I think it could help to make the system a little more complex and interesting.
An example of a way in which a player might try to 'crack' the system:
- Select sphere to use = MURDER
- Select target = WALL
- Select intonation = HAPPY
With a friendly wizard. Now obviously you have several contradictions here, what with murder implying killing something, happiness implying not killing something and wall being something which can't be killed. Perhaps the destructive effect of the murder sphere would be lessened by the happy intonation, with an end result of little bits of the wall being chipped off. Perhaps the spheres would have definitions, so murder would be associated with both life and destruction, so that if you apply it to a non-living thing there are still the destructive effects.
