Thunderstone Weaponry

Thunderstones have been used as akind of stun-grenade for centuries. A lump of alchemical material with a minor enchantment, they explode on impact and produce a terrible noise. Within the bowels of several ruins, thunderstones of massive size and unusually regular shape have been recovered for years. They were assumed to be used for demolition, or perhaps hurled like the boulders Giant’s are fond of today.

The expedition five years ago found their real use. A cache of weapons preserved by ancient wards that use Thunderstones as a propellant, and launch balls of cast lead at incredible velocities. The weapons are devastating, and their secrets have now been unpicked and applied to a variety of smaller firearms. The original weapons have been adapted by the Kingdom of Breland to arm her flagship, a brand-new airship called “Imperial Fire”. Karrnath’s thunderstone cannons are unaccounted for, although they have come out with similar weaponry almost as quickly.

All thunderstone weapons are breach-loading, which means that they load from the back of the barrel by means of a hinged mechanism. The ball is loaded first, followed by a leather wad, and then the thunderstone is loaded last. The breach is then closed, and the weapon is ready to fire. All Thunderstone weapons are counted as simple, and any class with Crossbow proficiency also has Thunderstone weapon proficiency.

All thunderstone weapons are reloaded using a move equivalent action, meaning that you can fire every turn provided you remain still. This provides a rate-of-fire advantage over crossbows, and is one of the primary reasons for their rising popularity.

Thunderstone Rifle

These weapons are the most recent introductions, produced in Zilargo. They have a magically forged barrel with rifling thread that increases accuracy considerably.

Thunderstone Pistol

Thunderstone Pistols have been extremely popular among the merchant classes, and sailors. They require almost no training, and provide excellent killing power at close to mid range. Rifled duelling pistols are also produced, with a longer barrel and more complicated loading process, and they do much greater damage over longer range. They also require an exotic weapon proficiency in order to reload in combat, however.
