Immediately before performing a Casting Attempt with a Wizard in a unit containing one or more models with Sacrificial Offerings, you may inflict 1 hit against that unit. This hit wounds automatically with Armour Penetration 10 and with no saves of any kind allowed. If a Health Point loss was caused against a model with Sacrificial Offerings, the Casting Attempt gains a +1 Casting Modifier. Each unit can be affected by Sacrificial Offerings only once per Magic Phase.
