I played one of my first games with trolls against cygnar the other day, and I realized 1 horrible thing. I had a centurion harrowing me with Arcane Shield on it... Sitting pretty at ARM 24. Even an enraged Mauler would have some issues taking this guy down. My question is not how do you defeat ARM 24, but how do I get rid of spells and animii?
In Warmachine, I play Mercs and Menoth and there are several ways to neutralize upkeep spells and what have you. What do trolls have as a counter-magic model/unit? I found 2 that rhyme the Thrullg and Mulg, but the Thrullg is a little laser focused. Mulg doesn't cancel out upkeep spells, but does prevent them from being cast.
Is the achilles heel of trolls the magic wand?
