Flame Jet Gauntlet

Pulled from the ashes of Bhelnir Darkheart, following his death and psionic explosion, all that remained were the bronze limbs that had been crafted in place of Duergar flesh. Amongst them and most notable, was that of the gauntlet where his forearm and hand should have been, from where a stream of fire was project in a 100ft line to devastating effect.

Investigating the gauntlet, it becomes clear that the gauntlet is a delicate mixture of psionic power and arcane, and no mechanical or clockwork mechanisms can be used to harness the power of the gauntlet in its current state. To wield the essence of the fire elemental within the gauntlet, only the advanced and well-trained power of the mind can be used to unleash its fiery potential.
Taking the gauntlet apart piece by piece, mapping out the blueprints to the design and spending hours drawing up ways in which magic items, both common and uncommon, could be used to spur the evocation magic into action, finally a potential outcome is found. It would require time, patience and an expenditure of resources but with a conduit that replaces the need for psionic power and the use of the arcane in its place, the flame jet gauntlet could be used by a spell-caster.
Whilst the item would only be able to be used by an artificer, the following benefits could be used upon its creation and attunement.

Weapon, Rare (Requires attunement by an Artificer)
The gauntlet spews flames in a line 100 feet long and 5 feet wide. Each creature in the line must make a DC 16 Dexterity saving throw, taking 18 (4d8) fire damage on a failed save, or half as much damage on a successful one.
Upon each use, a recharge requires a successful 6 roll on a 1d6.
If upon the recharge roll the result is 1, the gauntlet jams and cannot be used until the next rest.
=== Crafting ===
2500gp in materials, 30dt and a successful DC16 INT Tinkerer's Tools check.
