Hardened Casing Any Titan’s weapon can be upgraded with Hardened Casing for +5 points. Each of the Titan’s weapons must be upgraded separately. A weapon with this upgrade increases the Armour roll needed to achieve a Weapon Disabled Damage effect by 1 (e.g., a Reaver Arm Melta Cannon with this upgrade would need a 11+ instead of a 10+). After this weapon suffers a Detonation (X) damage effect, this upgrade has no effect for the remainder of the battle.
