Only change I made was to give forgemasters the rune domain as well as artifice as it seemed to fit thematically (even though the domain would not normally fall under torag). It made sense that the dwarven clerics that put runes on things would have access to those powers. It also helps to address that some people were upset that they were stuck with only one domain, and it's artifice.
I do like the idea of this separate sect of dwarven clerics as crafting for dwarvens often times holds the same devouting one might associate with religion.
