Bakkenroth Steam Spear

A silvered spear of solid design and impressive craftmanship, possibly dwarven or dragon-born in origin due the quality of the weapon. There is a grove at the edge of the spear tip, suggesting that the spear can easily be mounted on a shield for an effective combination of war gear. Now revealed to you a grove on the side of the staff has a bolt which can be shifted in to two different positions, which one fires out the tip and the other recalls it. The weapon seems to use a type of magnetism and enchantment of elemental air magic to fire the spear tip, Tor'Axian says that it can piece up to a metre of concrete, that is yet to be seen.

Fire Spear - Action 

You can fire the spear tip through a trigger mechanism along the handle, sending the spear tip at an immense speed through built up pressure in the spear. The carved sigils pulse for a few seconds before firing out up to 50 feet and 5 feet wide out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 4d6 Piercing damage on a failed save, or half as much damage on a successful one.

You then have to use an Action to reload  by sliding  the bolt on the side of the spear, which reverses the magnetic pull and reattaches the spear tip, from wherever it went and whoever it went through. 

 

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