XENOS HUNTER
Against the Kill Team's declared prey, this fighter re-rolls failed Wound rolls and ignores the cover the prey takes — a hunter so drilled against the named alien that neither its hide nor its hiding place avails it. Once per battle, when this fighter shoots any Brute or large enemy, its special-issue ammunition counts as Hellfire for that attack, auto-wounding the monster on a 2 or better regardless of its Toughness. This is the Watch's chapter skill, the discipline that replaces a Chapter's own — the study of the kill made second nature.
