Executioner

When making a Combat Attack roll against an enemy with 4 or less Life remaining, the Executioner may reroll any of their Combat Attack dice.

The Executioner starts the battle with a Justice score of 0. Everytime they slay an enemy model that has dealt any damage to your cabal, you gain 1 Justice. Each time you make a Combat Defense roll, you may increase the result of a single die by an amount equal to the Executioner’s current Justice.
