Right, but Humakt and Yelmalio are not on the known list of cults that allow sorcery. Jeff answered that Eurmal, Lhankor Mhy, Issaries, Chalana Arroy and many others are possible, but that we need to wait for the new GoG to obtain the full list. Of course, we know that the invisible God and the Seven Mothers are in the list, but for the others, we have to speculate. My personal guess is that Humakt may allow in Oktorion and perhaps in the Aeolian church of Heortland, but not Yelmalio.
