Hellfire Shells

Use this Stratagem in your Shooting phase, when an ADEPTUS ASTARTES INFANTRY model from your army shoots with a heavy bolter, a hellstorm heavy bolter or an executor heavy bolter. You can only make one attack with that weapon this phase, but if a hit is scored, the target suffers D3 mortal wounds and the attack sequence ends (if a hit is scored against a MONSTER unit, that unit suffers 3 mortal wounds instead of D3).
