The purpose of Black magic is to bring an end to life and well-being, through the metaphor of darkness.
The purpose of Golden magic is to restore life and well-being that has been destroyed, through the metaphor of the Golden Body, flesh and blood.
The relationship among these magics, alignment, religion and morality is complicated at best, and depends heavily on the world travelled to. For now, accept a promise to sketch out some ideas later that fit the Schools into varying worldviews, from Christian to Pagan to Taoist.
I use general categories here of "Holy/Unholy" things and creatures, which you may define at will. But one of the key decisions that can't be ignored when describing magic effects in the theology of a campaign is whether the two are:
- symmetrical, so that Holy and Unholy each have special virtue against each other,
- or asymmetrical, so that Holy things are effective against Unholy things but Unholy things don't especially affect Holy things any more than they affect other things, and maybe even less.
The essence of these Schools can be summed up in these variations on a popular first level spell. Yes, Cause is ranged and not touch (but you get a save); it should be one of the baddest damage spells out there, not something that requires you hit and does as much damage as that mace you are holding in your hand that by the way also doesn't require a saving throw.
Protection from Light Wounds
White, Level 1
Duration: 30 minute
Range: 0 (Touch)
By touching a being, the caster protects him or her from any form of damage to hit points other than permanent drain. The protection will negate the first 1d6+1 hit points of damage taken by the being from any source within the duration, rolled openly. The spell also protects, while it lasts, from an additional and equal amount of hit point damage from black magic attacks or from physical and spiritual attacks from Unholy creatures. Tally this amount separately, subtracting unholy damage from it first, before the more general pool is tapped.
Cause Light Wounds
Black, Level 1
By pointing at a living being, the caster inflicts a horrible wound in the flesh if the target fails to save (CON bonus). The wound does 1d6+1 hit points of damage. [Double this amount if the being is Holy.]
Cure Light Wounds
Gold, Level 1
Range: 0 (Touch)
By touching a fleshly living being, the caster heals him or her of 1d6+1 damage.
