The Army Scythe

The Army Scythe is a powerful light crossbow sold at the Thunderhammer Smithy. It is also called the Light crossbow of Speed. This crossbow has the highest rate of fire compared to all light and heavy crossbows, because it has rate of fire per round of two, but The Guide has a higher thaco and adds more damage to projectiles. Like many powerful weapons, it is also quite expensive.

In-game description
"Light crossbow of speed: 'The Army Scythe'. A short-lived human outpost in the Frozen Forest unearthed this weapon, and many others, from the ruins of an ancient settlement deep within that cold land. Never knowing the names of their extinct benefactors, the colonists used these tools to carve a large territory for themselves, though in the end it was for naught. Crushed by a superior number of Hobgoblins, these unfortunate souls have joined the ancients in their anonymity."
