In the Spellcaster Creation document for custom magic types, on the Source Factor chart, under the Cost of Variance line there's a discrepancy. The blank example chart gives Healing a variance of 500 and Illusion a variance of 1000, while the three worked examples give Healing a variance of 1000 and Illusion a variance of 500. I suspect the worked examples are correct, but would like to know for sure before I get any farther on something.
Healing at 1,000 and Illusion at 500 is correct. This was fixed in the full issue.
