I will mention one thing: there's a reason most of us have few or no Boons.  (Right now I am, in fact, regretting the purchase of the one Boon my character has.)  Numerically speaking, Epic Attributes are a lot cheaper with your starting points than with XP compared to Boons,<em>and</em>Epic Attributes tend to be a lot more powerful than Boons.<br/><br/>There's nothing wrong with having Boons.  Indeed, I recommend having a Relic that gives you access to some Purviews.  But only start with Boons if they're concept-important or if they're actually one of the good ones (like Wind's Freedom).
