The Hearthguard Berzerkers are the elite version of the Vulkite Berzerkers. They’re tougher in smaller numbers than an equal number of Vulkites if a hero is nearby. I chose to give mine the poleaxes for some mortal wound action.
Ten models seems to be the sweet spot for a smaller unit size. Any bigger and the points discount for the full 30 models starts to look tempting. Smaller and they won’t live long enough to be effective.
Paintwise they’re very similar to the Vulkites. I let the poleaxes be the distinguishing characteristic, rather than via the paint scheme.
The Grimwrath Berzerker gets the same slate chip base as other characters to give him a bit of separation from the rank and file dwarves that he may be hanging out with. I wasn’t feeling very adventurous with the hair, so the rest of the paint scheme is pretty pedestrian.
In game I love this guy. He gets to attack twice if he kills enough and rolls well enough the first time. The only problem is that he tends to clear the models around him, so I have a hard time consolidating into more enemies.
