CF’s ‘Jack Cracker Explosives
It is undeniable that the demand for serricsteel, both normal and quenched, are in high demand for anti-’jack purposes. Although many Rhulic smithies are thrilled at the increase of production and sales, Glenrock Copperfist brooded long and hard in his office, thinking about a cheaper, yet equally effective way to defeat ‘Jack plating. Although technically a failure, yet still one of his favorite inventions, the old weaponsmith would often be seen twirling his Masterkey Pistol between his fingers, and it was the fiery Incinerator charges for this weapon that inspired him to create what he would proudly call the ‘Jack Cracker Explosive Device.
The components of the weapon are deceivingly simple, yet the application and results can be devastatingly brilliant. Starting with what is essentially a heavily reinforced steel bucket or bell, this canister is filled with roughly an entire rifler’s pound of blasting powder, and nearly twice that amount of incendiary powder over it. The final layer is actually a concave plate of brass, secured in place by an iron ring. The rear part of the ‘bucket’ has a small hole drilled into it for a clockwork detonator, not unlike the kind found on grenades. When complete, the whole package looks nothing less then a giant, 10 pound grenade with a shiny bottom, but the results of this device are much more sinister then its appearance.
Essentially, the ‘Jack Cracker is a shaped explosive charge that turns a copper plate into a molten projectile capable of tearing through metal as if it were rice paper. When the detonator ignites the charge, all of the explosive force of the powder is focused in one direction. With all the force of the blast, and the heat of the incendiary powder focused at the copper, all of this energy turns the plate into a superheated bolt of slag that melts its way through just about any form of fabricated material.
Due to the unwieldy nature of the weapon, its application is best suited in defensive or premeditated tactics. In other words, this device can either be used as a mine with a pressure sensitive trigger, or as a bomb with a magnetic clamp that locks onto the frame of a machine.
‘Jack Cracker Stats:
Damage- 3d10 piercing / 3d10 fire
Range- 5ft (melee touch)
Critical- 18-20 x3
Special- Ignores all hardness
Mine Configuration: The ‘Jack Cracker must be placed into the ground and covered over with dirt, foliage, or other debris with a Craft (Nature, Geography, or Tactics) check, and every success of 2 over the DC carries over to the difficulty of it being spotted (minimum DC 10). This action takes at least 2 full rounds with a DC (16), and every extra round used to hide the device lessons the check by 2 (Minimum DC10). The fuse can then be attached to either a tripwire, a lever, or other pressure sensitive device needed for the enemy ‘Jack to activate. A Craft (Demo) DC (14) can be used to arm it, or a Craft (Mechanika) DC (16) can be used to arm it with 2 Standard actions. A rogue or similar class with the trap-finding ability can arm it with a Move action. When a ‘Jack trips the fuse, it is entitled to a Reflex Save (DC16) for half damage.
Saboteur Configuration: Instead of the device needing to be hidden with a pressure sensitive fuse, the Cracker is mounted to a steel frame with 4 magnetic cylinders. This process may be slightly noisy, as the strength of the magnets needed to hold the device solidly to the target may make a loud clang, which can be noticed with a Listen check of (DC10) in a 30 ft radius. A Strength or Dexterity check (DC16) used to carefully place the device onto its target may increase the Listen Check (DC12). Once secure, a trip wire or timer may be used to arm the weapon with the same checks or DC’s as above. If the device goes off while the ‘Jack is deactivated or unaware of the Cracker, this attack is considered an automatic critical hit with no save.
