Malevolent Artifice
(Rule)Description: 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+.
