Epic Roleplay: Random Armies

This is something to assist in solo campaigns or as a tool for random encounters, not yet usable with Tyranids or Genestealer Cults:

Step -1: Faction
Before randomly generating the army composition, the faction to which the army belongs has to be determined. This should usually be a direct result of game events or be informed by another random tool (such as one to generate faction active on a planet).

Step 0: Total Strength
The total strength of the army in points is determined by rolling a number of D6 and multiplying the result by 100. The number of dice to be rolled could be random itself, be informed by game events, or derived from other factors (e.g., see the way Mighty Empires determines initial strength based on controlled area and settlements therein).

Step 1: Army Core
Out of all the company cards which cost less than the total strength, one is randomly determined. This is the first company card of the army. The points still availabe are now equal to total strength less the cost of the company card.

Step 2: Determination of Additional Troops

Step 2a: Card Type
D6: 1-3 support card; 4-5 company card; 6 special card
If the type of card determined does not fit within the army, because the maximum allowed number of cards has already been reached, the roll is repeated.
If within the type of card determined, there are no cards whose points value is equal or lower to the available points, the roll is repeated.
