C'tan Shard of the Nightbringer

In its Shooting phase, in addition to using Powers of the C'tan, this model can target one non-vehicle enemy unit within 12" to which it has line of sight. The unit suffers a number of Wounds equal to 3D6 minus its Leadership, resolved at AP2 and with the Ignores Cover special rule. If at least one unsaved Wound is inflicted, the C'tan Shard of the Nightbringer immediately regains one Wound lost earlier in the battle.

Units containing one or more models with the Fearless special rule automatically pass Pinning, Fear, Regroup tests and Morale checks, but cannot Go to Ground and cannot choose to fail a Morale check due to the Our Weapons Are Useless rule. If a unit has Gone to Ground and then gains the Fearless special rule, all the effects of Go to Ground are immediately cancelled.

If a model with this special rule suffers an unsaved Wound from an attack that inflicts Instant Death, it only reduces its Wounds by 1, instead of automatically reducing its Wounds to 0.

When moving, this model can move over all other models and terrain as if they were open ground, and automatically passes Dangerous Terrain tests. However, it cannot end its move on top of other models and can only end its move on top of impassable terrain if it is possible to actually place the model on top of it.

This model has a 4+ invulnerable save. If it is ever reduced to 0 Wounds, before removing the model as a casualty, each nearby unit (friend or foe) suffers a Strength 4 AP1 hit for each model it has within D6" of this model.

If a model has this special rule, or is attacking with a Melee weapon that has this special rule, they always Wound on a 2+ in close combat.

Similarly, if a model makes a shooting attack with a weapon that has this special rule, they always Wound on a 2+. 

In either case, this special rule has no effect against vehicles or buildings.
