Malevolent Artifice (Dark Blessing)

At the end of each of the controlling player’s turns in which a model with this upgrade inflicts at least one unsaved Wound or Hull Point with a weapon with the Melee type, it gains the It Will Not Die (6+) special rule until the end of the battle. If the model already has the It Will Not Die (X) special rule, it increases the value of X by 1, up to a maximum of 4+.

At the end of each of your turns, roll a D6 for each of your models with this special rule that has less than its starting number of Wounds or Hull Points, but that has not been removed as a casualty or destroyed. On a roll equal to or greater than the number in brackets associated with the special rule, that model regains a Wound, or Hull Point, lost earlier in the game. For example, a model with It Will Not Die (5+) would regain a lost Wound on the roll of a 5 or more.
