If the wizard and surrounding models are wounded with a template are they allowed a ward save or regeneration roll? Can't see no in the book, but can't see yes.

Yes you can take a ward or regen. You could even take an armour save, mind you the high S of the hit would normally negate the armour. The miscast table does not state no saves of any type allowed.

Thought so Preacher ... thanks for the confirmation.
