Luminous Calendula Resources A material used for Resonator Ascension.

A rare bloom found only on the Sanguis Plateaus, said to thrive where warriors have shed their blood. When Gladiators die a glorious death in Septimont's wild hunts, their companions often place a Luminous Calendula at their graves as a solemn tribute to their courage and sacrifice.
