Hyper-growth Bolts

When you give a model this Relic, select one bolt pistol, boltgun or combi-weapon (see Codex: Chaos Space Marines wargear lists) that model is equipped with. When a model with this Relic shoots with that weapon, you can choose for it to fire a Hyper-growth bolt. If you do, you can only make one attack with that weapon, but that attack always wounds on a 2+ (unless the target is a VEHICLE unit) and has a Damage characteristic of 4.
