Arcwelder of Renewal

This compact, rune-etched magical welder channels divine energy and focused arcane heat through a reinforced nozzle. Originally created by forge-clerics and battlefield artificers, the Arcwelder of Renewal is designed to repair construct allies and scorch armored foes with brutal efficiency.

Function:

As an action, you can expend one use of this item to target a creature within 5 feet:

• Construct Creatures:
  The target is repaired by magical welding sparks, regaining 1d6 + your spellcasting modifier hit points. Gears realign, armor plates fuse, and joints are reinforced with arcane precision.

• Non-Construct Creatures:
  The target takes 1d6 + your spellcasting modifier fire damage from a concentrated blast of heat and flame.

  • If the target is wearing metal armor, the armor superheats violently. The creature takes an additional 1d8 fire damage and must succeed on a Constitution saving throw (DC = 8 + your proficiency bonus + your spellcasting ability modifier), or suffer disadvantage on attack rolls and ability checks until the start of your next turn. This effect does not require concentration.

Uses & Recharging:

The Arcwelder holds 4 charges. These charges do not regenerate automatically.

During a long rest, you may spend 30 minutes to recharge the Arcwelder by melting down small amounts of metal (such as iron or copper). For each charge restored, you must expend 1 unit of copper or iron, which is absorbed into the device's core.

Unused charges are lost at the end of a long rest and must be refilled manually each time.

Notes: To attune to this device, a creature must spend 1 hour studying its complex mechanisms and practicing its use. During this time, the creature must use the item to join or repair at least one piece of metal or construct, infusing it with a spark of arcane or technological energy. Once attuned, the user can activate the device with a thought and gains an intuitive understanding of its heat control and bonding precision.
