An error was discovered in the example character in the Arcanum PDF and print volumes. This is a very minor error (the character's strength is listed as providing a +2 damage bonus when it should be a +1 bonus).
This error was caused by the fact that in the earlier editions, Strength had an odd, one-off scaling that was not in line with the standard attribute save scaling or the Constitution hit-point bonus scaling. When I simplified and unified this, I failed to update the sample character to reflect this.
The errata sheet has been updated. The working files have been updated. When the next version of the PDF and print volumes is released, this fix will be present.
Thanks go out to Community user Thkaal for pointing this out! Kudos!
