Weapon Pattern

A Pattern unlocks weapon crafting, introduced in Destiny 2: The Witch Queen. You get Deepsight Resonance from weapon drops (a red-bordered icon); filling its attunement bar or dismantling the weapon yields Pattern progress, and you usually need several copies, for example five Deepsight Austringers, before you can craft. Crafting happens at the Relic in the Enclave on Savathûn's Throne World. Tutorial: Foundry Resonance. See Deepsight.
