We aren't done with the Khazad yet, we will be adding some UU's to them. But I thought I would talk a little about the changes that are being added to them in 0.14.
Non-magical:
The Khazad's greatest handicap, they cannot build Conjurers, Mages, Archmages or Summoners. They can still make Adepts and their Druids learn Earth Sorcery and Summoning spells instead of Nature Magic.
Ingenuity:
All upgrades cost the Khazad half as much as the other Civs.
The Dwarven Vault:
The Khazad judge their leaders by the amount of gold they are able to amass. The Dwarven Vault represents this amount. It will be upgraded automatically depending on the amount of Gold per City (GpC).
000-049 GpC: Dwarven Vault (Empty): -2 Happy
050-099 GpC: Dwarven Vault (Low): -1 Happy
100-149 GpC: Dwarven Vault: No effect
150-199 GpC: Dwarven Vault (Stocked): +1 Happy
200-299 GpC: Dwarven Vault (Abundant): +10% Hammers, +2 Happy
300-499 GpC: Dwarven Vault (Full): +25% Hammers, +2 Happy
500 or more GpC: Dwarven Vault (Overflowing): +25% Great People, +3 Happy, +40% Hammers
So if a Khazad player has 2000 gold and 10 cities he would have 200 Gold per City (GpC) which would earn him a free Dwarven Vault (Abundant) in each of his cities.
