'Hierophant' is the title given to an army's highest-ranking Liche Priest. It is the Hierophant who awakens the Tomb King's legions from their ancient slumber and, without their magic, the spirits of these warriors will be dragged back to the Realm of Souls.

The HierophantURL Copied!
Your army must include at least one Liche Priest to be its Hierophant. If your army includes several Liche Priests, the Hierophant will be the one with the highest Level of Wizardry. If two or more models have the highest Wizard Level, you may choose which one is the Hierophant when writing your muster list. You must tell your opponent which model is your Hierophant before deploying your army.
Should the Hierophant be slain, the magical animus of the army starts to dissipate. As soon as the Hierophant is removed from play as a casualty, all friendly units with the Nehekharan Undead special rule lose the Regeneration (X) special rule.
In addition, at the end of the phase in which your Hierophant was removed from play as a casualty, and during each of your Start of Turn sub-phases for the remainder of the game, all friendly units with the Nehekharan Undead special rule that are currently on the battlefield must make a Leadership test. If this test is failed, the unit loses a number of Wounds equal to the amount by which it failed the test.
For example: Your army's Hierophant is destroyed during your opponent's Shooting phase. At the end of that phase a unit of Skeleton Warriors (Ld 5) makes a Leadership test and rolls a 7 (failing the test by 2). That unit immediately loses two Wounds. During your next Start of Turn sub-phase, the same unit makes another Leadership test, this time rolling a 6, resulting in the loss of one Wound.
