Ways to stop the Minions:
Grimnak - Chomp
Braxas - Acid Breath
Deadeye Dan - Ullar Enhanced Rifle
Sudema - Stare Of Stone
Counterstrike - Probably those with 5+ defense
I had a castle game the other day; Utgar vs Einar, and i had 3 squads of these guys. I moved all of the squads close to the castle but out off firing range, then i moved one squad in the first round and took out some of the romans, Imperium and Tagawa Archers. The next round i moved another squad and took out even more figures. They are great when attacking weakish figures (when on the same level) because they have 6 defense. They can easily turn a castle game to the offensive players advantage.
