Hellforged Deredeo Dreadnought

A unit with this ability has a 5+ invulnerable save against Shooting or Overwatch attacks, and a 4+ invulneralbe save against Melee attacks in the Fight phase.

If this model is reduced to 0 wounds, roll a D6 before removing it from the battlefield. On a roll of a 6 it explodes and the hellish energies at its core are unleashed. Each unit within 6" suffers D3 mortal wounds unless it is a Psyker, in which case it suffers D6 mortal wounds instead.

At the beginning of any turn, the controlling player may declare that the helical targeting array is active. While the helical targeting array is active, the Hellforged Deredeo Dreadnought may not move, Advance, or charge in any phase, but adds 1 to its hit rolls for targeting vehicles with the FLY keyword. The helical targeting array remains active from the start of the turn in which their use is declared until the beginning of the controlling player's next turn. The helical targeting array may be activated any number of times during a game, but not in consecutive turns.

At the end of each Fight phase, roll a number of D6 for this model equal to the number of models that were slain by it during this phase; for each dice that scores a 5+, this model regains one lost wound. This model cannot regain lost wounds by any other means.
