This trinket drops from The Forgotten Experiments boss in Aberrus the Shadowed Crucible raid.
It is a passive effect trinket that increases your secondary stat of choice and resonates to your party / raid members a small amount of your chosen stat if they have the trinket equipped and are attuned with a different Oathstone (different Resonance buff). To get the most out of this trinket as a group, you will want to try to have at least one of each Resonance buff.
Dragonflight Oathstones Buffs
To select your buff, you must stand close to the Oathstone of your choice and use the trinket. Once the channel has finished, you will be attuned with that Oathstone and receive the respective Resonance buff.
Each Resonance gives you a fair amount of a specific secondary stat, except the Black Dragonflight Resonance, which gives all secondary stats instead of only one, but a smaller amount of each. The amount of stats the buff gives you is based on the item level of the trinket.
