Slayers of Karak Kadrin
Slayers of Karak Kadrin, also known as the Slayer Army of Karak Kadrin, is a variant Dwarf army for Warhammer Fantasy 6th edition released as part of the Storm of Chaos event. This army represents an enormous gathering of Dwarven Slayers, prompted by the massive encroach of Chaos into the Old World, although theoretically they could just as easily be used against other forces of sufficient size and dwarf-hate, like against the Orcs & Goblins (especially Grimgor's 'Ardboyz) or the Skaven.
Army Special Rules
"Look, Snorri, Trolls!" - A Slayer Army gets to roll an additional d6 and discard the lowest result when rolling to see which army goes first. Additionally, immediately after all deployments are complete, but before the first turn, every unit and character in a Slayer Army gets to make a free move 2d6" inches, with a single wheel to avoid terrain or another unit. During this bonus movement, the Slayer Army gets to ignore all terrain rules apart from Impassable Terrain.
A Glorious Death - Every model in a Slayer Army slain by an enemy unit with a Strength and/or Toughness of 5+ grants the Slayer Army +10 Victory Points to determine if they are victorious. This does include models slain by impact hits from chariots and monsters with Charge Attacks, but not models slain by chariot crew or monster riders (unless they have the requisite Strength/Toughness).
Dispel Dice - In addition to the normal Dispel Dice generation of a 6e Dwarf Army, a Slayer Army generates a further +1 Dispel Dice for every 1,000 points being played.
First Among Slayers - In a Slayer Army, one character must be designated as the Army's General, and counts as such for all purposes (namely, scoring Victory Points). If a Daemonslayer is present, they automatically become the army's general. The special characters Ungrim Ironfist and Garagrim Ironfist obviously take precedent, since that's their special rule.
Wards of Grimnir - Slayer Characters can spend 30 points of their Runes allowance to gain Magic Resistance 1, which also applies to any spell cast by a wizard within 6" or targetted within 6" of the warded Slayer.
Slayer Skills
These special skills can be taken in addition to Dwarven Rune Items. A Slayer Hero can take 1 Skill, whilst a Daemonslayer can take 2 Skills.
Deathblow: If killed in close combat, the Slayer gets to make their full allotment of attacks before being removed as a casualty, even if they already attacked that round. Costs +20 points.
Killing Blow: Grants the Killing Blow ability, duh. +25 points.
Beastslayer: Wounds inflicted by a Slayer with this skill are doubled when counted towards Combat Resolution (except those inflicted as Overkill in a challenge). +25 points.
Vampireslayer: Against creatures with Toughness 5+, each unsaved wound inflicted by this slayer is multiplied into d6 Wounds. +45 points.
Skavenslayer: The slayer gains bonus attacks equal to how many enemy models are in base contact with it - this doesn't work in challenges, can only give the Slayer up to 10 Attacks, and the Slayer can't gain more than 10 Attacks even if they are wielding an additional hand weapon or have attack-granting Runes. This ability costs 60 points for a Dragonslayer and 80 points for a Daemonslayer.
