Whilst browsing the Rick's Warmaster site today, I saw in the "what is new" section, that there was a link to a handy automatic army selector for Warmaster.
Created by Dave Susco, the army selector actually helps to build armies for Warmaster, Warmaster Trial Armies, Warmaster Ancients, and a few of the Warmaster Ancients Army book armies.
Not only does it have the rules for army building, and the upgrades, and various alerts about having 1 of x per 1000 points, it also has the ability to save and print lists, and when you print out a list, it has options to include all the stats, special rules or just the ones used, rules for magic items used, and spells (provided you are playing Warmaster Fantasy!).
It does not appear to have the additional special units added to Warmaster Fantasty, such as elite handgunners, or the Swordmasters of Hoeth, but considering those are both rare and OOP, it is to be understood.
Anyway, this Warmaster Army Selector is pretty handy if you are into any of the official Warmaster variants, or just like to play around with list making.
