Rules: Hunter's Eye, Fire Frenzy!, Unrelenting Advance
Hunters Eye: If an enemy is retreating from an assault or has failed a moral test and moves within Centrus' line-of-sight, he takes a few pot shots at them. Centrus fires his weapon at the squad using its first profile.
Fire Frenzy!: Centrus may use this ability during the shooting phase. When used, any unit he is attached to equipped with bolters(Storm Bolters, Bolters, Bolt pistols, Heavy Bolters, etc.) are able to fire an extra shot in the shooting phase. However, they are unable to do anything during the assault phase if this rule is invoked.
Unrelenting Advance: Centrus may exchange his heavy bolter for his personal boltgun, Terrorfang. Terrorfang has the following profile:
S5 AP 4 Rapid-fire, Master-crafted, 24" range.
In addition, he can now use the special ammunition rules that Sternguard squads use. However, he must be attached to a Sternguard squad or this rule cannot be used.
In addition, he adds a new ammunition:
Flamer Template, S5, Ignores Cover, Assault 1
Razorfang shot was created by a rather unhinged Abyssal Jaws artificer, who decided to fill a bolter shell with shrapnel and explosives. The shot leaves the barrel, travels a few feet, then explodes, causing a wave of heated metal shards to wash over the enemy.
