The Triple Threat (Patreon)

Weapon (laser pistol), very rare

A bulbous metallic firearm sporting rings of rotating arcane runes allowing for a variety of magical effects. This weapon can hold up to 3 charges. A creature touching this weapon can cast a spell and choose to channel their magical energy into the batteries of this weapon. If so, the spell has no effect and this weapon gains a number of charges equal to the level of the spell slot used.

Set To. As an action you can spend a charge and select one of the following beams to fire:

Scorch. A searing laser soars towards a target within 60 feet of you. On a hit, the target takes 3d6 fire damage. Hit or miss, the laser then explodes. The target and each creature within 20 feet of the point must make a DC 18 Dexterity saving throw, taking 6d6 fire damage on a failed save, or half as much damage on a successful one. The explosion spreads around corners and ignites flammable objects in the area that aren't being worn or carried.

Jolt. Shocking electricity screeches from the barrel as an electrical beam originating from you that is 60 feet long and 5 feet wide. Each creature in that line must make a DC 15 Constitution saving throw, taking 2d6 lightning damage and becoming stunned until your next turn on a failed save. If the creature fails its save by 5 or more, it is paralyzed until your next turn. On a successful save the creature only takes half as much damage and is not stunned.

Freeze. An unbearable chill encapsulates your foes in a 30-foot cone of cold originating from you. Each creature in that cone must make a DC 16 Constitution saving throw. On a failed save the creature takes 3d6 cold damage and becomes covered in ice for 1 minute, or until it or another creature within reach of it uses an action to break the ice. While covered in ice the creature's speed is reduced to 0. On a successful save, the creature takes half as much damage and isn't covered in ice.

Advanced weaponry, by virtue of its existence, sows strife and jealousy. With the ability to loose a myriad of elemental projectiles, a weapon such as this can dominate the field of battle. Through sleet and fire and spark the battlefield is transformed into a whirlwind of chaos and magic.
