Undead are no longer immune to poison. The reference to unliving targets in the poison description means chariots, war engines, buildings, and such like.

Any wounds caused by the Black Coach model (including wraith and nightmares) count towards this total.

No. Each summoned unit is a separate unit.

Yes. Check the Errata for Fast Cavalry.

The Blood Dragon with the highest Leadership in a combat must always issue challenges and must always accept enemy challenges if possible. If two (or more) Blood Dragon Vampires with the same Leadership value are in a combat, the Vampire Counts player may choose between them.

They only ignore movement penalties, that's all. This includes marching in difficult terrain.

Yes. The ethereal special rules specifically state "ethereal creatures block line of sight normally".

She can target any one unit in range; no exceptions are listed.

Yes. The answer is based on the following: 1) The Banshee has a special rule called "Single Model" which indicates that she is treated as a character on foot for movement and when targeted by missiles. 2) The Laws of Undeath for the Vampire Counts army indicate that a character on foot may always make march moves. 3) The Unit Strength and Single Model's Movement chart in Warhammer Chronicles 2003 indicates that single roughly man sized models on foot move "As Skirmishers". Regarding movement, units which move "As Skirmishers" have no need to turn or wheel, can pivot on the spot with no penalty, and have a 360 degree arc of sight for charges, etc. They do not incur penalties for difficult terrain/obstacles, and can march even if within 8" of enemies at the beginning of the turn.

No. While they count against the magic item allowance for characters, Bloodline Powers are NOT defined as magic items.

Yes. Ghouls are not classified as Undead. They have their own special rule called "Alive!" which does not prohibit them from fleeing from a charge.

Yes. No exemption to taking panic checks for DoW / RoR units has been granted in the Vampire Counts Army Book. While the units may be "Undead" they are still considered "friendly" units for purposes of Panic.

The intention of the rules is that no, Undead units cannot be joined by non-Undead characters and vice versa. This is the reason that everything in the Vampire Counts book is Undead (why Necromancers are Undead in his edition, for instance) - the only exception (and i'm talking main list here, not the appendix variant lists) being Ghouls - where it is explicitly stated that they cannot be joined by Characters for just this reason.

In the Warhammer Annual 2002.

Yes it can.

Only a roll to hit is needed.

No. It specifically states in the spell "once the spell is cast, choose any point within 18" and place one model on it".

This question is not specifically answered in the Vampire Counts Army book, but has been answered in the Tomb Kings Army Book under Djedra's Incantation of Summoning (which we recommend adopting for use with the Invocation of Nehek) as follows: "Rank and file models are added to the front rank until the front rank reaches at least four models. Then additional models may be added to either the front rank or they can be added to create rear ranks. If the unit already has more than one rank, new models can only be added to rear ranks."

The Victory points value of the new unit is based on the initial 7 Skeletons. Invocation of Nehek indicates to immediately calculate and record the Victory points value of the new unit when it is created.

The Black Periapt allows you to swipe a single unused magic die (your opponent's or your own) at the end of one Magic Phase and make use of it in the next one.

No. The staff only affects your own units.

No. Items like this only work for the mount as well if specifically stated.

Oops. A Lahmian or Necrarch cannot choose any armour, mundane or magical.

Yes. "Wight Blades" is actually a special rule which applies to the various types of mundane weapons that the Wights carry. If Wights on foot choose to use their hand weapons along with mundane shields, they qualify for the bonus.

"Wight Blades" is actually a special rule which applies to the various types of mundane weapons that the Wights carry. The Wight Blades special rule indicates that the mundane weapons carried by the Wights all have the the Killing Blow special ability attached to them. The Wight Blades special rule also makes the mundane weapons carried by Wights count as "magical" for purposes of being able to wound ethereal creatures, able to hit certain characters who are protected by magical armour, etc. but they still retain their mundane property. So a magical item which negates the affects of magical weapons would stop the attacks from Wights counting as "magical", but would not stop the Killing Blow ability attached to them.

It doesn't. Vaul's Unmaking only affects Magic Items. Wight Blades are not magic items.

As the "Wight Blades" special rule states that the Killing Blow and the ability of the weapons to count as magical are attached to the mundane weapons carried by the Wights, the Wights would no longer benefit from either of those special rules. In additon, as they would be striking with their fists, they would not receive any strength bonuses from weapons or be able to receive the +1 Armour Save bonus for using a hand weapon and shield.

Yes.

At least one model being raised must be within 6" of the marker, and no model may be within 1" of an enemy unit. If it is not possible, to position a newly raised unit as such, no unit may be raised. If the raised models are being added to an existing unit, then at least part of the existing unit must be within 6" of the Grave Marker.

Yes. Just as when trying to raise any other unit, if less than five models are created, the spell has failed to work and no models are placed on the table.

In an Army of Sylvania, replace Skeleton units with Sylvanian Militia units and Zombie units with Sylvanian Levy units when casting Invocation of Nehek. These units may be armed with any option allowed to Militia or Levy units (e.g. a Militia unit would have light armour and could be armed with a spear and shield, a halberd and shield, or a crossbow).

Sylvanian Militia come with light armour and shield, and either a spear or a halberd.

Yes, unless they were moved in the same magic phase via Vanhels Danse Macarbre, Sylvanian Milita may fire their crossbows on the turn they are raised. Note that models raised via Invocation of Nehek do not count as having moved.

Yes. All models are considered to have hand weapons, unless it is specifically noted otherwise (e.g. the unit's entry would have to state that the unit is not armed with hand weapons, or only armed with claws, etc.)

No. Dogs of War / Regiments of Renown are not listed as an option in the army list.

Yes! He is the ruler of Sylvania at the time of the campaign.

Mannfred counts as one Von Carstein Vampire Lord for Grave Marker purposes. While including him in an army takes up a Lord and two hero slots, he does NOT satisfy the 1+ Von Carstein Vampire Thrall requirement.

No. No reference is made to Vlad or Isabella in the Storm of Chaos materials and the realm of Sylvania was different during the reign of Vlad & Isabella than it was during the Storm of Chaos campaign. When fielding Vlad & Isabella it is recommended that players use the Von Carstein appendix army list in the Vampire Counts Army book as it represents the make-up of the army of Sylvania during their reign.
