Need some rules help...

* What are the different sources of DoW rules?

I know about regiments of renown (?)...and the DoW added as Rare to each army type. But is that only good for RoR?

* Where I am going...is there some other list o rule set that allows different armeis to mix or ally? For example, taking non-RoR units of Ogres in O&G? Or Dwarfs in Empire?

Hey Sheck,

Sorry for the delay in answering (I've been slacking on the boards a bit lately).

The Ogre Kingdoms Army book allows for units of Ogre Bulls, Ironguts, Leadbelchers, and Maneaters to be fielded as Dogs of War units in other armies. Each one takes up a rare slot in an army allowed to field Dogs of War, with the exception of Maneaters who take up two rare slots.

You can download the current Dogs of War rules from GW here:
Employing Mercenaries Download Page - GW (link, clicky, clicky)
This includes units of Dwarfs, Cannon, Heavy Calvary, Skirmishers, etc.

Hope that helps.

Cheers,
V.
