A few people have been asking me about this since the last game, so I've added it back in. If you would like to buy boon, you will now find the form to do so on the Boon tab of your character sheet. As before, the transaction is automated, but the boon award has to be done by hand, so please allow Jennifer and I a day or two to award any boon you purchase.
As a side note, I still intend on doing some fairly extensive revisions over the next month. Thus, if you're considering a respend, you might want to hold off until the changes are complete.
