This metallic rod has yellow and blue lines running up and down the structure, giving it a distinct look. There is a nozzle at the end.

As a bonus action, you can activate this item with a button. A short blue flame begins to shoot out from the end with a nozzle. This flame can burn through flammable material; it takes 1 minute to melt a hole in a 1-inch-thick wall of metal. It can also be used to weld metallic objects together.

When used as an improvised weapon, this item deals an additional 2d6 fire damage to the target.
Once per long rest, as an action, you can blast powerful blue flame out of the end at a target up to 60 ft. that you can see. The target must make a DC 15 Dexterity saving throw or take 5d6 fire damage and be lit on fire, taking 1d6 fire damage at the beginning of its turn. It can spend an action to extinguish the flame. The target takes half damage on a successful save and isn’t lit on fire.
