Hi, Verce can do both ally and warband when rallying.Yes, as per the Vercingetorix paragraph of rule 3.3 you may rally the ally/citadel and warbands in any order. So first you can rally an ally and then when you count how many warbands you place the ally is already there and would be included in the count.
Can he do the ally first, and then count it for the warbands ?
I.e. in a region where Verce is alone, he would place first the ally, then 3 warbands (1 leader, 1 ally, +1 )
thanks in advance
