Here are revised artha rules for use with Burning Wheel. The original system works just fine. These work better.

also, a revised character sheet to accomodate the new info:

Both of these are currently in beta test.
Enjoy!

Had a brief chance to review the new version, a couple of comments.
I like the cost increases in this version. However in the wheel chart on page 6, the costs for an Epiphany listed are for the original values.
As for the character sheet, is there a way (perhaps under skills) to track how much artra has been spent for a particular skill.
