Recently I was designing a spell and came upon an interesting dilemme about how to interpret the base individual of Terram.
The spell in question is important so here it is, for purposes of understanding the dilemma:
The engravers relief
ReTe 10
Range: Touch, Duration: Mom, Target: Part.
This spell creates a relief or engraving upon the surface of a stone. This spell is a craft magic spell, as it does the same work as could be done by a mundane stonecarver/engraver. The result of the spell is the creation of a Bas-relief upon the surface of a stone.
Base 2 (from covenants p. 51), +1 touch, +2 part, +1 stone)
The question is: How big a relief can this spell create?
The naive answer to this question is "a base individual of stone".
Th problem with the naive answer arises because the spell has an effect that is mostly two-dimensional with a Target of "Part", but the base individual is three dimensional. So how does the 3D invidiual transform down into 2D?
Note: The choice of target is because I want to cast the spell on larger rock formations to create engravings, e.g. on mountainsides, inside caves, etc.
I have come up with two possible interpretations, which I call the "platic position" and the "Minecraftian position" respectively.
The plastic position is that the spell can affect one cubic pace's worth of stone, but that this cubic pace can stretch, such that the maximum amount of relief creates is equal to the maximum depth of the relief multiplied by the surface area of stone covered by the relief.
The minecraftian position is that the spell can extend over the surface of a cube 1 pace on each side and to a depth of as much as one pace. This happens because the spell is T:Part, and the part is interpreted to be 1, minecraft style block of stone in the larger mass of stone that the part belongs to.
There is a sort "sub-position" to the minecraft position, which states that the spell affects a sphere with a volume of 1 cubic-pace.
Which position do the rest of you favour and why? Perhaps a different one entirely?
