Activating the Relic has awakened Resonant weapons and activated latent features of others. These weapons can be obtained through world drops and activities and contain Deepsight Resonance that must be attuned so the Resonant Materials can be extracted. 

Resonant Materials are used to improve your Shaped weapon or shape new ones.

Weapon Patterns are primarily obtained through Deepsight Resonance, and occasionally as a reward from specific quests.
