This expansion provided the following models (the "new one" having special restrictions):
- 1 Might Cannon Unit (Base + Cannon + 2x Soldiers)
- 1 Men-At-Arms Unit (Base + 5 Men-At-Arms)
- 1 Imperial Knights Unit (Base + 3x horses + 3x riders)
- 1 Crossbow Unit (Base + 5x Crossbowmen)
- 2 Imperial Archer Units (2x Base + 10x Archers)
- 1 Imperial Lord Unit (Base + Lord horse + Lord Rider)
The "new" unit is the Imperial Lord. He is a singular Lord Knight model that rolls 5 combat dice, but only has one "hit point" (all other units, sans Ogre Champion, have 3)
No additional cards are added to the original Battle Masters deck. Imperial Lords piggy-back on Lord Knight cards, and the others move along with their designated troop movement cards.
The game's instructions suggest that adding an Imperial Lords expansion to the Imperial Army, and a Chaos Warband expansion to the Chaos Army (2 Ogre Champion unite, 4 Beastmen units, and 2 "Chaos Lord" units), equal the advantages.
Also, the instructions explain a "point system" method for setting up alternative Battle Masters games.
Using these rules, players agree on a "point total" (example: 72), and then spend the corresponding number of points to place each unit, careful not to exceed the "point total":
Chaos Army: Goblins(4), Beastmen (4), Bowmen (4), Orcs (5), Chaos Warriors (5), Wolf Riders (5), Ogre Champion (8), Champions of Chaos (9), Chaos Lord* (8)
Imperial Army: Men-At-Arms (4), Crossbowmen (5), Archers (6), Imperial Knights (8), Lord Knights (9), Mighty Cannon (10), Imperial Lord* (8)
