Dwarfs (including Chaos Dwarfs) flee and pursue 2D6-1" Instead of the normal 2D6".
Dwarf units may march even if there are enemy within 8".
Dwarfs are legendarily resistant to magic and a Dwarf army always adds two extra Dispel dice to its pile. A Dwarf army therefore starts with four dice plus one per Runesmith or Runelord in the army.
All units in the army hate Elves (any type) instead of Greenskins. No model may have a Dwarf handgun or Pistol
