Agreed on the fire!

Hot Water Bottle: Cold blooded commander avoids penalty in cold lands
Really Big Hot Water Bottle: Commanders army avoids penalty in cold lands
Flaming Torch (different version from yours): Gives unit 50/100% darkvision


Some other abilities that I think should be available:
- heresy
- extra hit points (armour probably)
- twin casting (lets mage cast twice per turn with high fatigue penalty)
