In studying the Waveworn Phenomenon, scientists discovered a substance called "Tacetite" that can permanently contain the energy of the "Remnant". When modified, it becomes a potent energy weapon for Resonators, able to harm the Tacet Discord.
Researchers found that the byproduct of processing the Tacetite weapons showed the inertness of acoustic reaction. It can be used as a high-strenght and stable defense synthesis material
Tacetite is the golden-black minerals we see jutting out of the ground all over the map. It is used as a source of energy. It’s considered part of the Waveworn Phenomenon and therefore a result of the Lament.
Tacetite has the innate property of being able to absorb frequencies.
A supplement that stores a large amount of Tacetite energy, its energy density can make most Tacetite weapons run fully. Many experienced Resonators usually pre-assemble this supplement for preheating to prevent weapon failures in intense battles.
