Wordman/WyldMagicMath
This page contains more nerdy detail of the math used to select the point totals needed for various circles of sorcery in theWordman/WyldMagicMath/WyldMagic system.
The points needed for each circle were determined using the average number of points per card drawn. For the first draw of the deck, this is computed as follows:
|| Card || Number In Deck || Points Per Card || Points Possible in Whole Deck || || Ace || 4 || 1 || 4 || || Two || 4 || 2 || 8 || || Three || 4 || 3 || 12 || || Four || 4 || 4 || 16 || || Five || 4 || 5 || 20 || || Six || 4 || 6 || 24 || || Seven || 4 || 7 || 28 || || Eight || 4 || 8 || 32 || || Nine || 4 || 9 || 36 || || Ten || 4 || 10 || 40 || || Jack || 4 || 0 || 0 || || Queen || 4 || 0 || 0 || || King || 4 || 0 || 0 || || Joker || 2 || 0 || 0 || || Total || 54 || || 220 || |||||||| Average points per card: 4.074 ||
Even though the math changes as cards are removed from the deck, we'll stick with basic assumption that four points will be generated per card drawn. So based on this, figure out costs for each circle:
- A minimally competent terrestrial sorcerer has Essence 3 and Occult 3.
- Doing nothing but channeling, he can choose three cards per action.
- Three cards would provide a bit more than 12 points.
- Under canon exalted, a terrestrial spell needs two rounds to cast (one for channeling, one for casting).
- Two rounds his of channeling would provide 24 points on average, from six cards.
- To make the average terrestrial spell take two rounds to cast, the point value would need to be greater than 12 but less than 24.
- Consider the following to figure out where in that range to set the limit:
- On average, only a quarter of the cards will be diamonds. Very roughly, this would mean 6 diamond points.
- Presumably, the average case would contain some lower average of, say, spade points, because spade face cards would more often be used to cancel spade points than diamond face cards would be used to cancel diamonds (which should basically never happen).
- The maximum of one round of this sorcerer's channeling would be 30 points.
- What percentage of three card hands generate more than 12 points?
- What percentage of three cards generate more than 12 diamond points?
- What percentage of three card hands generate more than 12 points when non-diamond face cards cancel the highest card they can?

Maximum Points
Drawing some cards prohibits the use of others. This changes things as cards are dealt (so I'm not sure averages from above really mean anything). In any case, there is a maximum number of points you can get drawing x cards per round. Since each hand eats the cards of a given rank, the rate points per round as you draw a "maximum hand" each round decreases. For example, when drawing four cards, the first round the maximum is four 10s. The next round, there are no more 10s, so the max would be four 9s. Drawing all cards gives 220 points total.
