My girlfriend decided to give the game a try and I'm quite happy about that. So I showed her the career cards and she choose the Initiate. No Problem at all, but I'm playing a dwarven only group and so I told her that dwarfs have no rules for clerics, but I will build some for her.
So my approach is quite KISS, "Keep It Slayer Simple"
I simply take the career card "Initiate" and put Race "Dwarfs" mentaly on it. For the Action Cards I will simply use the existing Human Gods.
So her Priest of Shalya will be a dwarf priestess of Valaya. All with purple robes, chainmail, shield and the traditional axe "Kradskonti". "Stone and Steel" of 1st Edition had rules for them, also some adventure starting points, like a quest to find a rare herb or take care of a remote mining outpost.
So the setup for the other Gods is also simple:
Grungni , God of Mining: Action Cards from: Sigmar or Myrmidia
Grimnir , Warrior God: Ulric
Valaya , Protector of Home and Heart, Healing and Brewing: Rhya or Shalaya
Gazul , Protector of the Underearth: Mórr
So to avoid cherry picking, let the player choose one aspect of his cleric and then let him stay that way. So she will be a protector of dwarfkind, smashing skulls with her axe, brew beer and protect the children. A dwarfs beer-wet dream come true.
