BoTD - Blessing of the Dark - Increases skill gain and speed. Seems to mirror Circle of Cunning and Wind of Ages exactly, for example, a 50 power cast of this seems to have the same effect as a 50 cast of both Circle of Cunning and Wind of Ages. - Wurmpedia (http://www.wurmpedia.com/index.php/Blessings_of_the_dark)
