Defiler

Models with the Daemon special rule have a 5+ invulnerable save, and also have the Fear special rule.

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 has not been removed as a casualty or destroyed. On a 5+, that model regains a Wound or Hull Point lost earlier in the game.

A unit composed entirely of models with this special rule can re-roll one or more of the dice when determining Run moves and charge ranges (such as a single D6 from a charge range roll, for example).
