"Hello All.
Take these as they are folks - to be trusted.
• The entire army benefits and suffers from all the special rules for the Undead.
• Vampires are more than just a character choice. Blood Knights, Black Coaches and the Varghulf are all Vampires and allow
Undead within 6†to March move, reinforcing the sense of the Vampire Counts army.
Corpse Cart:
• All friendly units within 6†can benefit from the Always Strike First rule
• Can be upgraded to incur a -1 casting penalty on enemy Wizards within 24â€ÂÂ, or to add 1 to the number of wounds healed by an Invocation of Nehek spell on a unit within 6â€ÂÂ.
• Corpse Carts are a Core unit.
Blood Knights:
• Ultimate shock heavy cavalry that will give Khorne Chosen Knights a run for their money: frenzied Vampire knights with three Strength 7 attacks each on the charge
• Vampire special rule allows units within 6†to March.
Varghulf:
• Bestial vampiric lone monster – impressive profile with Regeneration, causes Terror and subject to Hatred of everything!
• Vampire special rule allows units within 6†to March
Mannfred von Carstein:
• At his most powerful, Mannfred knows all the Necromantic spells and all
those from the Lore of Death
• Mounted on a Nightmare, can be used to represent Mannfred the Acolyte or Mannfred Count of Sylvania
Vlad von Carstein:
• Powerful warrior and wizard, and almost unkillable with the Carstein Ring
(4+ Ward save and returned to life after death on a 2+)
• Will go berserk if Isabella von Carstein is killed
Konrad von Carstein:
• Most powerful Hero level warrior-Vampire in the army list
• Hates everything, and stands a chance of succumbing to either Frenzy or Stupidity each turn.
Enjoy - such EVIL!!!!!!!!!"
