|Intact Sentient Core||Exceptional Sentient Core||Flawless Sentient Core|
Sentient Cores are Sentient objects that can be traded in for Standing with The Quills in Cetus. Intact Sentient Cores are dropped by Eidolon Vomvalysts while Exceptional Sentient Cores are dropped by Eidolon Teralysts, Eidolon Gantulysts and Eidolon Hydrolysts on the Plains of Eidolon, one for each Teralyst Synovia that is destroyed. They appear as white and blue orbs that float above the ground, lit up by a blue aura that makes them more visible, and marked with HUD icons much like Ayatan Stars. A Flawless Sentient Core is dropped upon successfully capturing (not defeating) a Teralyst, Gantulyst and Hydrolyst while it is tethered by the required amount of Eidolon Lures; both the Shards and the Flawless Core will be dropped by the Lures upon self-destruction, not by the Eidolon itself.
Since update Update 22.13 both Intact Sentient Cores and Exceptional Sentient Cores can drop from Battalysts, Conculysts and their decaying variants. This allows for progression with the Quills outside of the Plains of Eidolon.
Redeeming these Cores will gain Standing with The Quills and they are also used as a sacrifice for ranking up with them as well. Each Intact grants 100, each Exceptional grants 500, and each Flawless grants 1,200.
