The Radiant Stone is bright, glowing cube on the Sunstone Isle in Matumada. The Radiant Stone's heat will damage players the closer they get to it, quickly killing even the most armored adventurers who pass too close to it. It is advised to take caution when near this landmark.
The Radiant Stone has a secret feature that originally went unnoticed to the community.
