Walach Harkon

If Walach is included in your army, units of Blood Knights are taken as Special Units instead of Rare Units.

A model striking a hated foe in close combat re-rolls all failed To Hit rolls during the first round of combat. Sometimes a model will only Hate a specific foe. Where this is the case, the type of foe will be expressed in the brackets. In the case an enemy hates a certain faction, they have Hatred against all models from that army book. In addition, they must also re-roll successful rolls to restrain from pursuit against enemies they have Hatred against. If a unit would gain Hatred in a round of close combat after the first for any reason, treat this as the first round of combat for that purpose.

Whenever a model with this rule kills one or more enemy models in close combat, roll a D6 at the end of the Close Combat phase. On the roll of a 5+, the model recovers a single Wound lost earlier in the battle. This does not work against models with Animated Construct, Daemonic, Forest Spirits.

Vampiric models have Fear and Immunity (Psychology). In addition, enemies must re-roll successful To Wound rolls against them. This does not apply to Magical Attacks, Flaming Attacks, or successful Killing Blows.

The Vampire must always issue and accept challenges when possible.

If your army contains any Undead units, you must include at least one character that is Wizard that uses the Lore of Necromancy.

Slain General
At the end of the phase in which the General is removed as a casualty, and at the start of every friendly turn thereafter, all friendly Undead units on the battlefield must take a LD test. If the test is failed, the unit immediately suffers a number of Wounds equal to the amount by which it failed the LD test, with no saves of any kind allowed. These Wounds are distributed as if from a shooting attack.

If, at the start of any of your turns following the death of the General, there is one or more friendly Wizards on the table who know spells from the Lore of Necromancy, no unit in the army needs to take this LD test while at least one of them remain.

Characters who are not Undead may join Undead units despite not being Unstable themselves. Mounted Characters ignore the Undead rule of the mount. If an Undead unit would get destroyed as a result of Unstable, any remaning character(s) will need to take a Break test as normal the same phase, using the LD modifier that they lost the combat by.
