Unstable Core

Overview

Unstable Core was a currency from Destiny 2: The Edge of Fate, consumed when infusing gear above 200 Power. Dismantling gear above 200 Power yielded them, more for higher-Power items, and infusing two identical items cost only Glimmer instead.

Removal

Update 9.1.5.2 (22 October 2025) deprecated Unstable Cores, replacing them with a flat cost of one Enhancement Core and 5,000 Glimmer at all Power levels; they are no longer granted from dismantling. Bungie said they were too restrictive and did not drive interesting buildcraft.
