SANGUINARY ONSLAUGHT
When this fighter makes a charge, it re-rolls failed Wound rolls in the ensuing melee, the Thirst turning the assault into butchery. If the gang is locked in the Assault doctrine, the fighter also adds +1 Damage to the first melee Damage roll of that fight — the killing edge sharpest when the whole host has surrendered to the charge.
Once per battle a Champion may declare the Onslaught a gang-wide call, extending its effect to all friendly fighters within 6". The Chapter's chosen skill, the swap that marks the Sons of Sanguinius apart: where other Astartes drill for cohesion, these warriors drill for the moment the blade lands.
