Thunderspark

Thunderspark is a relic. Usually securely housed in the heart of Titanstrike, it powers the rifle, harnessing the essence of storms and focusing it into concentrated blasts of energy. The rifle's power source can also be credited to Mimiron, who devised it for his comrade, Keeper Thorim, in ages past.

• Reverberation (quest)
• The Huntsman's Creed
• Paid in Blood

• Despite being mentioned in Titanstrike's lore since Legion, it was only added as an item in Battle for Azeroth (as it powered the rifle, and was thus part of it).
