The enemies of the Undead feel their limbs become heavy and their hair turns grey. They collapse, unable to support themselves as death catches up with them.

Curse of YearsURL Copied!
Remains in play. The Curse of Years can be cast on any one unengaged enemy unit within 24".
If successfully cast, the enemy swiftly starts to age. Roll a dice for each model in the affected unit. A model will suffer a wound on the roll of a 6+. No armour saves are allowed.
Once it has been cast, the spell remains in play. It lasts until it is dispelled, or until the Wizard decides to end it (which he can do at any time), attempts to cast another spell or is slain. If not dispelled, at the beginning of the caster's next Magic phase, models in the affected unit suffer a wound on a 5 +. In the caster's next Magic phase they will suffer a wound on a 4+ and so on, to a minimum of 2+. No armour saves are allowed.
Characters who are part of a unit affected by this spell stop suffering from its effects if they leave the unit.
