None. I own the core rulebook, dragon-blooded, sidereal, abyssals, player's guide, savant and sorcerer, scavenger sons, and kingdom of halta; but I have not yet had the opprotunity to play.
I suggest having botches count as successes for the dodge roll. So, if a solar uses this charm and anticipates his opponent performing some elegant dodge to avoid the attack, but instead trips on a rock or something, I think the solar should miss. After all, the solar knew exactly where to strike.
