“Thunderspike,” is a brutal weapon that combines the piercing power of a spear with the rapid, concussive force of a jackhammer.

The weapon has a long, reinforced metal shaft designed to withstand the recoil of its mechanism. The spearhead is made of a durable, sharpened alloy, shaped into a broad, triangular point for maximum penetration. Behind the spearhead, a cylindrical chamber houses a compact piston system powered by arcane energy, 

Along the shaft, grip points are insulated with shock-absorbing material to prevent the vibrations from affecting the wielder. A trigger or activation switch near the handle engages the jackhammer function.

How It Works:

1.Piercing Mode: 1d6 piercing damage 

When used as a traditional spear, the Thunderspike functions like a standard thrusting weapon, capable of puncturing armor and flesh with its sharp point.

2.Jackhammer Mode: 5d6 piercing damage

Activating the jackhammer mechanism causes the spearhead to rapidly oscillate forward and backward in short, powerful bursts. This motion mimics the action of a jackhammer, amplifying the spear’s piercing and destructive power.

•Armor Penetration: The rapid strikes create repeated impacts at the same point, allowing the spear to punch through heavily armored targets.

•Structural Damage: Against rigid surfaces like stone or metal, the jackhammer function can shatter or weaken the material.

•Critical Strikes: When used in combat, the vibrations can cause severe internal trauma, even if the spearhead doesn’t fully pierce the target.

3.Stabilization Features:

•Recoil Dampeners: A system of internal shock absorbers ensures the wielder can maintain control of the weapon during prolonged use.

•Charge Management: The weapon requires brief cooldowns to prevent energy depletion.

Usage in Combat:

The thunderspike is devastating in close quarters, particularly against heavily armored foes or fortified positions. However, its weight and reliance on a power source make it less suitable for prolonged engagements.

Optional Enhancements:

•Explosive Tip: A secondary charge can be attached for added devastation on impact.

•Modular Design: Detachable spearhead for switching between piercing, slashing, or bludgeoning options.

This hybrid weapon is the epitome of raw power and ingenuity, perfect for characters who want their attacks to strike fear and awe into their enemies.

 

Proficiency with a Spear allows you to add your proficiency bonus to the attack roll for any attack you make with it.
