Black Powder ‘Command’ rule amendment Sunday, Aug 23 2015 


Never been happy with the statistical likelihood for the various move probabilities in Warlord Games ‘Black Powder’.

Every commander on the table has a command value – usually in the range 7 to 9, but 4 to 10 is the total range; the higher the better. This can be modified for local conditions

When giving an order you roll 2d6.

Equal or 1 less – one move
2 less – two moves
3 or more less – 3 moves.

The problem is that this generally makes 2 moves the LEAST likely, which seems odd. You expect

i) 1 move most likely, 3 least, or
ii) 3 moves most likely, 1 least likely, or
iii) 2 MOST likely.

All 3 can be rationalised – increasing likelihood, or ‘2’ being the ‘ground state’. 2 moves LEAST likely makes no sense.

So recently we trialled a modification. ┬áTo get 3 moves you must roll 3 less than target AND equal or under half, otherwise it stays as ‘2’

Examples

Command 9- 3 moves on 4 or less
Command 8- 3 moves on 4 or less
Command 7- 3 moves on 3 or less

The differences can be seen in this table
Combos is number of different ways to get this result of 2d6. For example Command 8 you get 1 move on a 8 or a 7. There are 6 ways to roll 7, and 5 ways to roll 8, so ‘8 combos’ out of a total 36.

1 9 25.0% 11 30.6% 11 30.6%
2 6 16.7% 5 13.9% 4 11.1%

As the downloadable one from Warlord games has a coloured back ground, an I don’t intend to use that much yellow ink, I made my own, sticking as far as practicable to their layout.
