This would obviously extend the alchemy idea - >the creation of poisons, herbal compounds and literally anything in >any state (which the PC was able to store). First thoughts on a representational model: Create a coordinate system. The axis of the coordinate system are the principles of your alchemy system (yes, lotsa dimensions). The purpose of the coordinate system is to define the behaviour of a substance. Given a substance, a coordinate location can be computed from its components. Given a coordinate location, the effect of the substabce can be derived. Thus the leaves of the herb WaggaWagga might have a coodinate weight of (-5, 8, 3) presuming the simplistic case of only 3 principles. The root of the UmbaUmba plant might have a value of (2, 9, -10). Mix then together with GooGoo mud (0, 0, 2), and you get a substance (-3, 17, -5). That location can be plotted in the coordinate system and a result computed: A minor weakening agent (-3) that also a *really* effective sleeping draught (17), and reduces physical dexterity (-5). Or some such similar whatever. You can then add other weightings, such taht the WaggaWagga(-5, 8, 3) gets an added (-2, 1, -8) value added if it is prepared by grinding in a special stone bowl while chanting the desiderata backwards. The reason for doing a coordinate system rather than a flat expression for each axis is tht it allows you to put in break values. Simple things like values on this axis smaller than X have this effect, and larger than Y have this totally other effect. Compound that across multiple axis, and you can get a result which is far removed from the intial components. Next up would be to then special case certain combinations (reflective alchemy), such that components A (which normally has a very simple effect), and B (similarly simple), in combination do something else entirely (ie mutate into a totally different coordinate. This special casing can be handled without undue difficulty by building it into the base system. Again, going back to the simplistic 3 principles above, just add various other "fake" principles after that. Thus WuggaWugga could be (-5, 8, 3, 0, 12, 2) and UmbaUmba (2, 9, -10, -5, 9, -10). Then when they're mixed the result is (-3, 17, -2, -5, 21, -8). Now you can do your special casing on the fake values (-5, 21, -8). Say things like if the first fake value is less than -5 it was apply (X,Y,Z) to the base matrix, it its over +5 apply (Q,R,S) etc. This results in a really simple way to codify the exceptions and and special cases while allowing new compnents to be added which have their own unique behaviours. >Has anyone actually attempted anything of this nature, or >contemplated it?
