This is my first list ever for Trollkins. I tested it today and it worked pretty well. Had a bit of trouble against Heavy 'Jacks, but the they eventually fell to an added Mauler.
Madrak Ironhide, World Ender.
- Dire Troll Mauler.
Trollkin Hero.
Fell Caller.
Krielstone Bearer and 3 Scribes.
- Stone Scribe Elder.
5 Trollkin Champions.
5 Trollkin Champions.
Swamp Gobber Bellows Crew.
The army deploys in a classic brick formation with the Champions taking point in a cresent formation. You can either put one line of Champions at point, with one unit just behind them or put both at point in a big single rank with the Hero in between them. Behind them should be the Gobber Bellows, Madrak and the Mauler with the Fell Caller just off to the side. Behind them the Krielstone Bearer unit and
UA. The trick is to keep everything within Madrak's CRTL zone and within the protective zone of the KSB. This gives the entire army a massive series of Buffs.
To make this look less complicated I clefted an image from Battlecollege:
The army is really fun to use and breaks face with much regularity. The Champions are double tough needing a P+S 26 weapon to kill one when they are in
BTB and a P+S 28 weapon when they are in range of the KSB. Add the tough roll onto this and you have a dirty tough unit. Oh wait, I have two and they all have TWO weapon master attacks. TWO!!! And they're fearless. The buffs this force can get is just sick - +1 Strength and +2 to hit. Madrak can also get +3
Str from The Mauler's Animus to make him a little more killy

, like he needs it when he has Vortex of Destruction and is able to kill as many living models as he has in melee range. So P+S 18 rolling 3 dice for
DMG = 29
DMG on average. He can kill anything he wants that lives and breathes. Oh and his feat is just awesome with the amount of
DMG his army chucks out.
On a side note, the Army is good with Primal Madrak with his buffing spells and pretty good with Borka Kegslayer when he uses Mosh Pit.
Any comments???
