The Murder Blade

Each time the bearer makes an attack with this weapon that successfully wounds the target, if the target unit has the CHARACTER keyword, that attack inflicts 3 mortal wounds and the attack sequence ends; if the target unit has the PRIMARCH or DAEMON PRIMARCH keyword, that attack inflicts D3+3 mortal wounds instead and the attack sequence ends; otherwise, the target unit suffers 2 mortal wounds and the attack sequence ends.
