More Command points in the new edition – both players will also receive the same amount according to the size of the game.
So, if you don’t earn Command points by taking additional Detachments, do they still interact with each other in any way? The answer is yes, but how they do so has been turned on its head. Instead of earning you Command points, each Detachment you take will instead COST you Command points. However, it’s worth noting that the Command points spent on a ‘core’ Detachment (Patrol, Battalion or Brigade) are refunded if it also includes your Warlord, so your first Detachment is usually free. An army drawn exclusively from the same Faction and comprising a single Detachment is the most strategically flexible on account of their experience fighting alongside one another, and therefore offers the most Command points.
The Battalion Detachment…
In each of your Command phases – the new opening phase of your turn – you will receive one additional Command point.
The core Stratagems available to every army have been increased to seven.
